As a physicist, I have to take my hat off to chemists. Yes, it is "just quantum mechanics of the last electron orbital" but it is also sooo much more. There is art, there is (immense, and I do mean IMMENSE) skill. Yes, in fundamental physics we do ten-decimal-places precision, but we mostly do it by trowing 10-digit sums of money at it (or more).

It's just a different scale, if you calculated the cost of the LHC per physicist, engineer and chemist who worked on it, it would be much more efficient in terms of accuracy per dollar per person. You could do some physics experiments at home for a couple hundred of dollars and get results of the same order of precision as a home chemist purifying their product to 99%+

When handling glassware it will accumulate a static charge. When you put the glassware on a balance and close the door the reading will take a very long time to settle and will drift because the static field is changing which changes how much weight it is applying to the balance. Hitting it with the anti-static gun drains the static field away and allows the balance to settle faster and reduces drift by a lot. Some of these balances also have an option for either an automated electric ionizer or a pellet of Americium (same element used in ionizing smoke detectors) to emit alpha radiation to drain the static field. I was actually a bit upset when my manager finally told me about this (I thought the gun had something to do with the HPLC vials lol) because I spent a day trying to figure out what was wrong with our balance. When I would put a volumetric flask on it the reading would just keep on drifting. After a few minutes it would be a couple mg off of what it used to read. I was putting test weights on it, and even left a test weight overnight, and the readings were always perfect. My boss then told me about the effect a static field has on the glassware and showed me the anti-static gun. Sure wish he told me about that a year earlier lol.
A fun fact about those anti static guns. They often use polonium. The same radioactive isotope the Russians used in that guy's tea. They need to be replaced fairly often because of it. Which makes polonium much more commonly available than people think.

@@seeigecannon Polonium is actually very common in these static guns. Polonium only really releases Alpha particles, which can be stopped with a good sheet of paper, or a few centimeters of air. This makes it extraordinarily safe when only externally exposed. Those alpha particles are actually what causes it to be "Anti-Static," alpha particles will react with negative ion charges that are accumulated from free electrons like the ones you accumulate from the difference in charge between your head and your feet, neutralizing them, and "killing" the static charge. The Russians got Litvinenko by getting him to ingest the polonium. Inside of his body, the alpha particles could wreck havoc on his organs, without protection from the air and his skin. Otherwise you could (theoretically) handle polonium bare handed, though that's not advised, because if you ingest it, you're Alexander Litvinenko.
I discovered you in 2014, and I can't believe it's already been ten years of watching you on and off. You and other channels have helped fuel and augment my curiosity and love for chemistry.
Dude I was about to comment close to the same thing. But for me its was later closer to 2016ish, maybe a bit later. When i started high school chemistry.
It's a similar story for me. I missed out on studying chemistry in high school because I chose to spec into the physics/engineering skill tree instead 😅
me too. i remember watching this guy in middle school. didn’t understand a word he said. took chemistry in high school and ap chem junior year. went to community college, dropped out. i still watch him at times
I found his channel in 2009 at the science madness forum. Back then a freshman major in chemical engineering. Since then I finished my degree, moved to another country, did a Master's degree and been working 3 years now. Still around!

As someone that manufactures semiconductor grade stannous salts, your glassware is cleaner than mine. Thanks for the tips on cleaning, oxidizing heat never occurred to me, I always went straight to the aqua regia.
The chloroplatinic acid is undoubtedly for Karstedt's catalyst, an important component for hydrosilylation. The reason they require a precise amount is because they don't have SEM-EDX or ICP-OES to assay the final % Pt, instead they can just have high confidence that they made the target %.
The more I think about it the more I think you're right. It would fit with the other stuff they are doing. And if I make it they get a single and consistent batch rather than order from sigma and not be certain every ampule is exactly the same as the others.
lol, sigma is fine. And if you pay the big bucks they can certainly provide matched ampules from the same lot with semiconductor grade precision. My friends probably realized they could get me to do it for them and get just enough precision for their needs without having to pay the much higher price that sigma demands.
I worked at a company that made Adam's catalyst (PtO2) that was used for hydrogenation. We started with an ounce of platinum wire (about $300 back in 1977) and as you described dissolved in in aqua regia, then precipitated the ammonium salt with NH4OH. This was mixed with sodium nitrate and fused - after copious clouds of NO2 were evolved, you're left with PtO2 in sodium chloride, which is crushed and dissolved in water. The Adam's catalyst is filtered, washed and dried. You can use it as a catalyst until exhausted, then dissolve it in aqua regia all over again. We did that a lot. So easy to make, can't imagine how it costs so much. I'm astonished that platinum is still so cheap....leas than a thousand an ounce, which considering how much of it comes from Russia is pretty amazing.
I have seen 0.001% Pt supported on charcoal blocks to be used as catalyst. At the end of life (dead catalyst because of poisoning) the catalyst can be recovered by burning the carbon in a furnace. Previously asbestos was being using a the support material. Soak the asbestos cloth in the H2PtCl6 solution and dry in a furnace.

4:30 Oh my God! Thank you! I've taken 3 chemistry classes, and recently finished my engineering degree, and in all that time, no one ever explained why we needed to use weigh boats on the scale!
Also using a boat makes it so much more convenient to transfer elsewhere. Can usually bend them to funnel smaller quantities of substances into flasks easily.
There's a lot of odd amalgams that can form this way, too. In the same way that gallium will destroy aluminum via amalgamation, so too can some other odd combinations of metals brought in contact. Some don't seem to have done anything right away, but have significantly weakened one or both pieces.
@dan43544911 I'm being 100% real. It made sense to me if we were weighing something loose like a powder. But if we had to weigh something like pennies or a beaker, it wasn't explained to us the importance of the weigh boat/paper.
I do IV drug compounding work in an ISO 5 cleanroom, while I would never come across your ampules, I certainly would trust nurdrage ampules after watching this video! Love your channel! Would buy a Nurdrage T-shirt or other merch too!
I appreciated how you made a video clip showing you, washing the bottom of the flask. Most people would say, "My camera flaked out" and move on. But people come here to learn, and I thought that, you showing that step, would be useful to people who haven't done that. Transfer losses (material sticking to the containers) reduces yields, so it's great you showed how to deal with this issue.
There's something so satisfying about watching a product deemed "professional grade". It really shows it's not just making the product but also verifying its mass (or whatever quantity you're interested in), packaging it multiple times, etc. Thanks for the video
Fantastic. I'm another one who can't believe that they just watched over 30 minutes of a guy making a chemical they've never heard of before. Great work.
From a fellow chemist who you took the time to give a few tips for recovering Pt from lab waste around 10 years ago, it is still awesome to see you working, my man. Great video!
Dude.... I always wondered how they fill these type of ampoules. Despite being an engineer myself i never figured out a logical visualisation until i saw in your video... This is fantastic. Thanks for teaching me stuff.
The amount of videos you did for amateur uses makes this all the more awesome. It's really nice to see how you do the procedures when it counts to more than just experiments.
Honestly my jaw dropped when you laid out all the sealed, labelled ampules at the end for display. That looks so god damn professional - I love it! You've pretty much made an artisanal style chemistry Christmas present that wouldn't look out of place in a chic small town apothecary that sells fancy soaps and tinctures. Only it contains a highly expensive and dangerous chemical instead of cherry-scented shea butter. I'm impressed! And c'mon...you can barely even see any misalignment in the labels. Don't even worry about it, lol *Chef's kiss*
I love this. he's invested a grand plus materials, supplies and a significant amount of time to help members of his tribe, gaining cred, future opportunities, a platform. Definitely worth watching to see how a master of a skill plays
I've watched your videos for well over 10 years now and you were a big inspiration for me pursuing chemistry as a career. Now I have a bachelors in biochemistry and I'm a Materials Scientist. Thank you for all of the great and entertaining videos over the years!
Many moons ago I was a friend of Alfred Bader, the founder of Aldrich Chemical back when Aldrich wasn't partnered with Sigma. He was such a friend to chemists everywhere, still remembered fondly by a few old timers. He wrote a great book about the history of Aldrich Chemical, an interesting read if you enjoy history....
I really enjoy filling ampoules and sealing them for some reason. There is something very satisfying about the hermetic seal, and the knowledge that your product is trapped in there for ever, as if it were a bug in amber.
on the warnings on pyrolyzing: If you're bougie enough to have a kiln/furnace with a programmable ramp/soak controller, (like people that make their own glass) you can (slowly) ramp even soda-lime glass up to 1000F (536 C) temperature, push it up to 800 for a second, and back it down (slowly) to "able to be handled with bare hands", and *not* risk shattering it from thermal shock.
My theory is that they are optimizing formulations of their catalytic process. In that case I'd want stoichiometric precision and a low price from my supplier. Presumably, your single batch process yields consistancy across your ampules. They can assay the quality of the first ampule they use so they only pay once for trust. With S-A they pay for that trust with every ampule.
I'd like to see a Pd/C prep along the lines of ua-cam.com/video/ZIme3liGVeo/v-deo.htmlsi=ytNvx1k8pS19GSDO. I went through the whole stack myself years ago - PdCl, dba from benzaldehyde, tri-Pd-dba, to the simple prep in the video. Not entirely sure how successful I was though. So much fun to put together multiple steps to a useful end product.
I really like this video as it shows that being a chemist is way more than just knowing the reactions and combining chemicals. The amount of preparation before doing a reaction or experiment takes way longer than the actual reaction itself. This video clearly shows that drafting protocols (and getting second opinions on protocols), preventing impurities by prepatory cleaning, Calibration and calculations all cost alot of time before doing any reaction. Additionally, some problem solving is shown (cleaning ampule necks). Maybe its not flashy, but it portraits really well what a chemist does. I can't imagine to do this myself if I also had to video it all 😅.
reminds me of my small stint as a compounding pharmacy technician many moons ago. All the prep and production that goes on in a lab without the knowledge, just follow pharmacist's printout and basic common sense
In my experience selling automotive parts, using vinyl labels instead of paper is a smart move. You do want to make sure that the ink/toner is covered by a layer of clear plastic, as some solvents can dissolve the ink. NEVER use ribbonless heat transfer paper, that stuff dissolves just by looking at it sideways. IDK why that is even legal to make receipts out of. Also, don't trim the bags so close to the heat seal. The extra border serves to protect the seal and allows you to reseal the bag if for whatever reason you need to do so.
I appreciate videos like this, while the reaction is the same, the addition of details about precise measurement and cleanliness of glassware is helpful. Amateur chemistry has taken off in recent years but there are few videos covering details like this, so I appreciate you helping to fill this niche.
I started watching your videos more than 10 years ago and always dreamed of being a chemist myself. Now, a “few” years later, I have received my Ph. D. in chemistry and still enjoy your videos. Keep up the good work! I look forward to many more exciting videos.
Always a good time when NurdRage uploads! You definitely have way more patience than I do when it comes to home chemistry...although I've never had a thousand dollars and a client/supplier relationship on the line, lol!
I have to admit, it is an utter delight to see how you do things so precisely that you can even account for evaporation rates of chemicals. It's a salve to a bruised soul, in a manner of speaking. Also, it would be interesting if you managed to get a sample run through a NMR system, if only for bragging purposes. That would show just how clean and pure you were. Speaking of trust though, the fact that you showed your "client" the protocols, and then published a video on the preparation of the reagent would go a heck of a long way to establishing that trust. The fact that you're willing to open yourself to that scrutiny speaks volumes of your character, and honestly, I'd buy from you if I were in the game.
The story of Troy weights are actually pretty interesting. It was the first standardized weight system used in a multi-national trading system in the Middle Ages. The Troy weight system was invented hundreds and hundreds of years before the metric system was birthed into existence, it can be dated back to Roman times. When used during the Middle Ages, a Troy ounce was equivalent to 480 grains of barley, something most could easily attain.
The amount of time I've spent converting units over the years adds up to a few hundred dollars in wages, and the psychological cost associated with repeated annoyance. I know what's already been lost by keeping different units for the same thing in use.

Hi nice one brought back some memory's working in a drug manufacturer sterile department years ago.All the ampules when sealed were tested in red dyed water under a small vacuum.This was human doses mind you.
I recently worked with chloroplatinic acid and I seem to remember that it is a photosensitive compound, isn't it? Granted it won't change the Pt mass in the vial, but if the exact molecule is needed for their application, there could be an impact on their synthesis... Great video btw!
yeah interestingly enough i asked them if i could give them 5g of platinum but as potassium tetrachloroplatinate, and they said no. Then i asked if i could give it as tetrachloroplatinic acid. (the (II) form rather than the (IV) form), and they said if i could package that, they would take it. I can't actually make it, but that's another clue.
I just wanna say that I’ve been here the entire time. I discovered your channel 13 years ago through a friend recommending a video you did. I’m glad you’re back we missed you.
Let me just say, I've really been loving these longer videos that go deeper into the nuts and bolts of chemistry. I'm not a chemist, so it's really interesting getting inside insight into all the procedures and details and side work involved.
I don't think you should underestimate the amount of trust you've developed by documenting your methods and the care you take. If I needed chemicals, I'd definitely think of buying Nurdrage brand, and I'd definitely rather give the money to you than Sigma bloody Aldrich

This video distills down the idea that the more you learn, the more you realize what you don't know. The PHD grade level of care and procedure demonstrated gives you faith in why humans are so cool. This is what were made of.
I was going to say weighing the beaker on an open scale would be affected by micro air currents, I can only assume multiple weighing's would average that out? My next lab (2nd year environmental chem ) is far below the quality shown here, will be to extract, purify and calculate the amount of copper in a given rock sample I have to add my thanks to you for these video, the quality, passion and humour is top notch. ("People with money don't care for the opinions of people with brains").
When I watched your first video making this compound (which I barely remember) I had zero work experience and no awareness of process control and such. So this time around I ended up thinking all the questions you answered with "and before you ask..." As far as the video being mundane work, I think it's still valuable because it's not something everyone would be able to see. There's not always a school field trip lab tour or "bring your kid to work day" and for us adults who aren't chemists and aren't friends with one this is the only way we'd be able to see it. So thank you for showing us something interesting.
A wonderful demonstration of why Chemistry and Science in general can be so expensive. Granted, I'm sure bigger companies have faster ways of doing this, (aka, more expensive equipment,) but all that comes at a cost too, I'm sure. Your attention to detail is inspiring regardless.
I second this! People think professional labs are all clean and tidy but the majority of the ones I have worked in throughout my undergrad were disgustingly dirty and would shock the average person to see.
Hey NurdRage, I've been watching you since the early 2010s. It's kinda crazy how much time has passed. Not a chemist, not even a hobby level one, but for some reason your videos are always super interesting and I can't help but watch!

Those alpha particles are actually what causes it to be "Anti-Static," alpha particles will react with negative ion charges that are accumulated from free electrons like the ones you accumulate from the difference in charge between your head and your feet, neutralizing them, and "killing" the static charge. The Russians got Litvinenko by getting him to ingest the polonium. Inside of his body, the alpha particles could wreck havoc on his organs, without protection from the air and his skin. Otherwise you could (theoretically) handle polonium bare handed, though that's not advised, because if you ingest it, you're Alexander Litvinenko.
I discovered you in 2014, and I can't believe it's already been ten years of watching you on and off.
You and other channels have helped fuel and augment my curiosity and love for chemistry.
Dude I was about to comment close to the same thing. But for me its was later closer to 2016ish, maybe a bit later. When i started high school chemistry.
It's a similar story for me.
I missed out on studying chemistry in high school because I chose to spec into the physics/engineering skill tree instead 😅
Same. I’ve been watching the Nurd rage for years. One of the best channels on YT.
me too. i remember watching this guy in middle school. didn’t understand a word he said. took chemistry in high school and ap chem junior year. went to community college, dropped out. i still watch him at times
I found his channel in 2009 at the science madness forum. Back then a freshman major in chemical engineering. Since then I finished my degree, moved to another country, did a Master's degree and been working 3 years now. Still around!
"I'm not actually selling these for money, I'm actually trading these for other chemicals I have difficulty getting, as well as future favors and good will. OK enough about basic economics..."
Truly a fascinating being
Looks like he has been in jail or in the army. Pretty much the same.
Are veterans typically blacklisted by chem suppliers? @@suprememasteroftheuniverse
@@suprememasteroftheuniverse nah... most people in jail or the army are incapable of understanding this... correlate of crimes and violence tells us that cops and criminals 90% don't pass mental acuity tests.... meaning they are literally not self aware. How could anyone possibly believe anything to the contrary? You think they hire people to carry guns because they can think and understand things? lol
@@suprememasteroftheuniverse how you figure that?
As someone that manufactures semiconductor grade stannous salts, your glassware is cleaner than mine.
Thanks for the tips on cleaning, oxidizing heat never occurred to me, I always went straight to the aqua regia.
How’s the semiconductor industry going in your country bro? I’m in the UK and it looks abysmal unless you’re in the EU/US/China
The chloroplatinic acid is undoubtedly for Karstedt's catalyst, an important component for hydrosilylation. The reason they require a precise amount is because they don't have SEM-EDX or ICP-OES to assay the final % Pt, instead they can just have high confidence that they made the target %.
The more I think about it the more I think you're right. It would fit with the other stuff they are doing.
And if I make it they get a single and consistent batch rather than order from sigma and not be certain every ampule is exactly the same as the others.
@@NurdRage shots fired at sigmas reputation!
lol, sigma is fine. And if you pay the big bucks they can certainly provide matched ampules from the same lot with semiconductor grade precision. My friends probably realized they could get me to do it for them and get just enough precision for their needs without having to pay the much higher price that sigma demands.
'I prefer the bulge'
Gigity
I have no idea what’s going on in this convo but I gotta say it’s amazing
I greatly appreciate you showing the extra steps to have a more pure and reliable product. Title is a lot less click baity than the original.
Yes, please. The passion is not just the ''cherry on top'' but the substance I look for. Great work👍👍🍀
can i have it in 5 gram ampules please?
I worked at a company that made Adam's catalyst (PtO2) that was used for hydrogenation. We started with an ounce of platinum wire (about $300 back in 1977) and as you described dissolved in in aqua regia, then precipitated the ammonium salt with NH4OH. This was mixed with sodium nitrate and fused - after copious clouds of NO2 were evolved, you're left with PtO2 in sodium chloride, which is crushed and dissolved in water. The Adam's catalyst is filtered, washed and dried.
You can use it as a catalyst until exhausted, then dissolve it in aqua regia all over again.
We did that a lot. So easy to make, can't imagine how it costs so much. I'm astonished that platinum is still so cheap....leas than a thousand an ounce, which considering how much of it comes from Russia is pretty amazing.
Can you share a bit detail of process ?
I have seen 0.001% Pt supported on charcoal blocks to be used as catalyst. At the end of life (dead catalyst because of poisoning) the catalyst can be recovered by burning the carbon in a furnace.
Previously asbestos was being using a the support material. Soak the asbestos cloth in the H2PtCl6 solution and dry in a furnace.
Are not sanctions on Russia's metals ?
@@bca-biciclindcuaxel7527 sanctions are very useful for the operators dealing with blackmarkets- once the legal channels are closed, these other operators start their operations for a modest fee. Of course politicians get a cut from the fees
@@bca-biciclindcuaxel7527sanctions dont stop exports, they just create middle men and slight cost raises
4:30 Oh my God! Thank you! I've taken 3 chemistry classes, and recently finished my engineering degree, and in all that time, no one ever explained why we needed to use weigh boats on the scale!
lol, i wonder if they know the reason. I find even some professionals forget, and just do it out of habit.
Also using a boat makes it so much more convenient to transfer elsewhere. Can usually bend them to funnel smaller quantities of substances into flasks easily.
There's a lot of odd amalgams that can form this way, too. In the same way that gallium will destroy aluminum via amalgamation, so too can some other odd combinations of metals brought in contact. Some don't seem to have done anything right away, but have significantly weakened one or both pieces.
Are you for real?
@dan43544911 I'm being 100% real. It made sense to me if we were weighing something loose like a powder. But if we had to weigh something like pennies or a beaker, it wasn't explained to us the importance of the weigh boat/paper.
I do IV drug compounding work in an ISO 5 cleanroom, while I would never come across your ampules, I certainly would trust nurdrage ampules after watching this video! Love your channel! Would buy a Nurdrage T-shirt or other merch too!
I appreciated how you made a video clip showing you, washing the bottom of the flask. Most people would say, "My camera flaked out" and move on.
But people come here to learn, and I thought that, you showing that step, would be useful to people who haven't done that.
Transfer losses (material sticking to the containers) reduces yields, so it's great you showed how to deal with this issue.
There's something so satisfying about watching a product deemed "professional grade". It really shows it's not just making the product but also verifying its mass (or whatever quantity you're interested in), packaging it multiple times, etc. Thanks for the video
Fantastic. I'm another one who can't believe that they just watched over 30 minutes of a guy making a chemical they've never heard of before. Great work.
From a fellow chemist who you took the time to give a few tips for recovering Pt from lab waste around 10 years ago, it is still awesome to see you working, my man. Great video!
Dude.... I always wondered how they fill these type of ampoules. Despite being an engineer myself i never figured out a logical visualisation until i saw in your video... This is fantastic. Thanks for teaching me stuff.
When I did Bromine I used a long 16 gauge needle and a 20ml syringe
The amount of videos you did for amateur uses makes this all the more awesome. It's really nice to see how you do the procedures when it counts to more than just experiments.
Honestly my jaw dropped when you laid out all the sealed, labelled ampules at the end for display. That looks so god damn professional - I love it! You've pretty much made an artisanal style chemistry Christmas present that wouldn't look out of place in a chic small town apothecary that sells fancy soaps and tinctures. Only it contains a highly expensive and dangerous chemical instead of cherry-scented shea butter. I'm impressed! And c'mon...you can barely even see any misalignment in the labels. Don't even worry about it, lol
*Chef's kiss*
I love this. he's invested a grand plus materials, supplies and a significant amount of time to help members of his tribe, gaining cred, future opportunities, a platform. Definitely worth watching to see how a master of a skill plays
I've watched your videos for well over 10 years now and you were a big inspiration for me pursuing chemistry as a career. Now I have a bachelors in biochemistry and I'm a Materials Scientist. Thank you for all of the great and entertaining videos over the years!
One thing that drives up price at Sigma is also that they test the purity, depending on the grade you buy. Analysis is expensive.
100%, assay costs are expensive, part of the price of "trust".
Highly agreed
This is the type of semi-professional basement amature chemistry that I find incredibly entertaining.
I work for Sigma-Aldrich, now a part of Millipore-Sigma... always nice to hear the company being mentioned
Many moons ago I was a friend of Alfred Bader, the founder of Aldrich Chemical back when Aldrich wasn't partnered with Sigma. He was such a friend to chemists everywhere, still remembered fondly by a few old timers.
He wrote a great book about the history of Aldrich Chemical, an interesting read if you enjoy history....
hope you don't lower their reputation :D
that's pretty sigma
Erm what the sigma
What a sigma
I really enjoy filling ampoules and sealing them for some reason. There is something very satisfying about the hermetic seal, and the knowledge that your product is trapped in there for ever, as if it were a bug in amber.
on the warnings on pyrolyzing: If you're bougie enough to have a kiln/furnace with a programmable ramp/soak controller, (like people that make their own glass) you can (slowly) ramp even soda-lime glass up to 1000F (536 C) temperature, push it up to 800 for a second, and back it down (slowly) to "able to be handled with bare hands", and *not* risk shattering it from thermal shock.
My theory is that they are optimizing formulations of their catalytic process. In that case I'd want stoichiometric precision and a low price from my supplier. Presumably, your single batch process yields consistancy across your ampules. They can assay the quality of the first ampule they use so they only pay once for trust. With S-A they pay for that trust with every ampule.
not a bad take. They did say something about optimizing a process. Yet another clue as to what they're up to :)
I'd like to see a Pd/C prep along the lines of ua-cam.com/video/ZIme3liGVeo/v-deo.htmlsi=ytNvx1k8pS19GSDO. I went through the whole stack myself years ago - PdCl, dba from benzaldehyde, tri-Pd-dba, to the simple prep in the video. Not entirely sure how successful I was though. So much fun to put together multiple steps to a useful end product.
I think they're cooking meth. It's the only explanation. 😂
@@thomasvanorman3963if meath was this hard to make people wouldn’t be able to make it in there kitchen wile high.
@@thomasvanorman3963yo, that new platinum ice is fire for realz, bit pricey though
I really like this video as it shows that being a chemist is way more than just knowing the reactions and combining chemicals.
The amount of preparation before doing a reaction or experiment takes way longer than the actual reaction itself.
This video clearly shows that
drafting protocols (and getting second opinions on protocols), preventing impurities by prepatory cleaning, Calibration and calculations all cost alot of time before doing any reaction. Additionally, some problem solving is shown (cleaning ampule necks).
Maybe its not flashy, but it portraits really well what a chemist does. I can't imagine to do this myself if I also had to video it all 😅.
reminds me of my small stint as a compounding pharmacy technician many moons ago. All the prep and production that goes on in a lab without the knowledge, just follow pharmacist's printout and basic common sense
In my experience selling automotive parts, using vinyl labels instead of paper is a smart move. You do want to make sure that the ink/toner is covered by a layer of clear plastic, as some solvents can dissolve the ink. NEVER use ribbonless heat transfer paper, that stuff dissolves just by looking at it sideways. IDK why that is even legal to make receipts out of.
Also, don't trim the bags so close to the heat seal. The extra border serves to protect the seal and allows you to reseal the bag if for whatever reason you need to do so.
I appreciate videos like this, while the reaction is the same, the addition of details about precise measurement and cleanliness of glassware is helpful. Amateur chemistry has taken off in recent years but there are few videos covering details like this, so I appreciate you helping to fill this niche.
lol your username
That's absolutely beautiful. The professionalism is so impressive
I started watching your videos more than 10 years ago and always dreamed of being a chemist myself.
Now, a “few” years later, I have received my Ph. D. in chemistry and still enjoy your videos.
Keep up the good work! I look forward to many more exciting videos.
LOVE that he showed the whole process even including calibration of the scale. Watching the whole workflow was very much appreciated by my OCD!
Always a good time when NurdRage uploads! You definitely have way more patience than I do when it comes to home chemistry...although I've never had a thousand dollars and a client/supplier relationship on the line, lol!
I have to admit, it is an utter delight to see how you do things so precisely that you can even account for evaporation rates of chemicals. It's a salve to a bruised soul, in a manner of speaking. Also, it would be interesting if you managed to get a sample run through a NMR system, if only for bragging purposes. That would show just how clean and pure you were.
Speaking of trust though, the fact that you showed your "client" the protocols, and then published a video on the preparation of the reagent would go a heck of a long way to establishing that trust. The fact that you're willing to open yourself to that scrutiny speaks volumes of your character, and honestly, I'd buy from you if I were in the game.
I just watched this whole video but I don't know why. Will never ever do this and hated chemistry at school. Enjoyed it. Thanks
The story of Troy weights are actually pretty interesting. It was the first standardized weight system used in a multi-national trading system in the Middle Ages. The Troy weight system was invented hundreds and hundreds of years before the metric system was birthed into existence, it can be dated back to Roman times. When used during the Middle Ages, a Troy ounce was equivalent to 480 grains of barley, something most could easily attain.
Thanks for the context around troy ounces! We lose something the day that _everything_ is measured in grams
The amount of time I've spent converting units over the years adds up to a few hundred dollars in wages, and the psychological cost associated with repeated annoyance. I know what's already been lost by keeping different units for the same thing in use.
Bro is making the finest compounds ever, meanwhile today my simple double displacement reaction to make potassium nitrate ended in a messy goop instead of any crystals
Came here interested in how you were sealing your ampules. Thank you for explaining this!!!
0:24 " rather than waste their time they agreed to waste mine instead " 💀
Hi nice one brought back some memory's working in a drug manufacturer sterile department years ago.All the ampules when sealed were tested in red dyed water under a small vacuum.This was human doses mind you.
I recently worked with chloroplatinic acid and I seem to remember that it is a photosensitive compound, isn't it?
Granted it won't change the Pt mass in the vial, but if the exact molecule is needed for their application, there could be an impact on their synthesis...
Great video btw!
yeah it is, but they said it wasn't an issue for what they were doing. it was more important i got in exactly 5g per ampule.
@@NurdRage Ok I see, thanks for the reply! At least we have one more clue about their secret project
yeah interestingly enough i asked them if i could give them 5g of platinum but as potassium tetrachloroplatinate, and they said no. Then i asked if i could give it as tetrachloroplatinic acid. (the (II) form rather than the (IV) form), and they said if i could package that, they would take it. I can't actually make it, but that's another clue.
I am not your friend but I appreciate them. If your "friends" doesn't appreciate them, change your friends. This is great work.

I just wanna say that I’ve been here the entire time. I discovered your channel 13 years ago through a friend recommending a video you did. I’m glad you’re back we missed you.
I just know someone a century from now will be holding and admiring one of these little tubes
Let me just say, I've really been loving these longer videos that go deeper into the nuts and bolts of chemistry. I'm not a chemist, so it's really interesting getting inside insight into all the procedures and details and side work involved.
I don't think you should underestimate the amount of trust you've developed by documenting your methods and the care you take. If I needed chemicals, I'd definitely think of buying Nurdrage brand, and I'd definitely rather give the money to you than Sigma bloody Aldrich
hmmm.... if i see more comments asking for it, i might do a second run for public sale. we'll see.
@@NurdRage just to say though, I don't need chloroplatinic acid in particular, I'm just saying that you have plenty of trust to trade on.
this is some high quality material, the way the shipping package was done is just perfect and it adds to the presentation.
Love the inclusion of procedures, very important science for the amateur that doesn't know anything, especially from someone so detail-oriented.
I think many of us would pay for a professionally produced NR vial of hydrogen oxide.

I understand the business point of view. In my youth, I sold naturally aged electronic components and tested and labelled them one by one. Over time, my components were the best available on the market.
If I ever have to switch back to it, I will, although the market has somewhat disappeared.

@@billballinger5622 I collected used dismissed electronics and removed carefully its components, tested each and sold them to whom paid exorbitantly amounts of money. Namely medical and military equipment producers.

Drop everything, NR uploaded guys
I've been watching you for over a decade. From the time you lost your lab and had to make a gofund me. I believe I suggested the gofund me. I am so sorry it wasnt a fever pitch success. You are the original Chem Chan.
The OG chem youtuber is back!
You are like a friend I've never met as I have been watching your channel longer than any channel that I can think of and I thank you for that.
19:58 you must have pretty interesting friends to make you do that. remember when you reacted a dead cockroach with potassium chlorate?
So meticulous! Impressed with your patience and precision and I had fun watching the process.
your videos are a gem
This kind of precision is called-for in the production of first-surface mirrors. Maybe your friends are using the Pt for that! I would also love to see how this ends up being used. Cool video
*Refluxing* aqua regia - now there's a phrase that would strike ... concern ... due concern ... into the minds of my school chemistry teachers. Who learned to check my work. "Aidan, before you try to clean that flask with *fuming* aqua regia, try ammonia water" (a weak alkali). Spoilsports!
So cool to see your work flow and project management, which is definitely not something I thought I'd ever say! I also absolutely love the over-the-shoulder view of an expert at work. Once again, you do a good service to young and becoming scientists everywhere, as well as crotchety hermits like me who've lost their edge...
25:40 This is how DNA and Plasmids are sold for Microbiological work.

I love seeing a professional from a field I'm not familiar with sharing the little tricks and processes of their work! I would never have thought that the bulbs on the ampules indicate that they had sealed before they cooled.
5:10 it is because Platinum is heavier than feather 😁
I used to watch your channel all the time when I was studying chemistry in college 10 years ago but lost the channel name when I switched you tube accounts. I'm so glad I found it again.

I'm here mainly for the entertainment value of seeing an expert do what they specialize in, I do appreciate the the learning of lab technics and procedures, witch can easily be ported to my own work and hobbies, so thank you for taking the time of producing this videos.

The cleaning process was actually sick! Thanks for including. (:
infinite money glitch?
Its called working 🤯
The attention to detail was inspirational.
I came here for the culture, and you did not disappoint! Great video, learned alot, thank you!
This video distills down the idea that the more you learn, the more you realize what you don't know. The PHD grade level of care and procedure demonstrated gives you faith in why humans are so cool. This is what were made of.
I was going to say weighing the beaker on an open scale would be affected by micro air currents, I can only assume multiple weighing's would average that out?
My next lab (2nd year environmental chem ) is far below the quality shown here, will be to extract, purify and calculate the amount of copper in a given rock sample
I have to add my thanks to you for these video, the quality, passion and humour is top notch. ("People with money don't care for the opinions of people with brains").
When I watched your first video making this compound (which I barely remember) I had zero work experience and no awareness of process control and such. So this time around I ended up thinking all the questions you answered with "and before you ask..."
As far as the video being mundane work, I think it's still valuable because it's not something everyone would be able to see. There's not always a school field trip lab tour or "bring your kid to work day" and for us adults who aren't chemists and aren't friends with one this is the only way we'd be able to see it. So thank you for showing us something interesting.
I love your attention to cleanliness. Crazy that an acid needs platinum bars to make😮Also the trust system you explained was a great thing to hear.
Since all things are metals at absolute zero, it's amazing to see a physical bar "vanish" in a transparent liquid. Awesome video.
Actually near absolute zero, you get Bose Einstein condensate, which is a fascinating material :)
watching this process of making chemicals and packaging them was very satisfying
As a packaging enthusiast I love how much effort was put into packing them.
A wonderful demonstration of why Chemistry and Science in general can be so expensive. Granted, I'm sure bigger companies have faster ways of doing this, (aka, more expensive equipment,) but all that comes at a cost too, I'm sure. Your attention to detail is inspiring regardless.
I second this! People think professional labs are all clean and tidy but the majority of the ones I have worked in throughout my undergrad were disgustingly dirty and would shock the average person to see.
Hey NurdRage, I've been watching you since the early 2010s. It's kinda crazy how much time has passed. Not a chemist, not even a hobby level one, but for some reason your videos are always super interesting and I can't help but watch!
I work in a plant that makes this material on an industrial scale. I've worked with it a handful times in the lab. Very cool to see someone else doing it.
This video is giving me flashbacks of Quantitative Analysis in college. Wonderful technique dude. A joy to watch an expert at his craft.
I just LOVE how you implement precision in your synthetic approaches. So meticulous and thorough. That's why you have always been my all-time-favorite Chemistry UA-camr
Outstanding! In addition to making the chloroplatinic acid, you've provided so many useful techniques. Plenty to unpack!
i have no idea why i watched this but its very interesting, i guess its just fun watching people do what they love
Nice treatment on synthesis and packaging, really relaxing and educational, never gets old hearing the WHY and watching someone practice the art.
A chemist i was working for one time, needed his old truck to pass the smog certificate renewal test. He looked among his Pt group metals on hand, (he did electrochemical precious metals refining)
Im not sure the details but i believe we used ruthenium acid salt solution and sprayed some into the carburetor while running the engine the idea was to end up with a born again catalytic converte.
