Review/Test of SH-2 Hot Plate Magnetic Stirrer
Вставка
- Опубліковано 22 сер 2024
- This is a review/test of the SH-2 hot plate magnetic stirrer. I purchased this for $51.80 on eBay with shipping included. For the price, I was skeptical and you never know exactly with eBay sometimes. A hot plate is extremely useful when conducting distillations and here I give some feedback on my first impressions and testing it by boiling water in a beaker. Overall, pretty pleased with it. I'll make a ton of other videos in the future once the rest of my distillation stuff comes in the mail and so I'll have plenty of other chances to make sure it works properly. The test begins at 3:00 minutes.
The fact is as i was told by a four E's representative,(We make all the copys you see with different labels! They pay us a fee for using their name on our products! ) so if you see the same mixer with different company names, there is only one company responsible for making it! Take care
I used it a few times with high temperatures. Today I wanted to heat up something and it just stopped working; I heard some weird sounds it seemed like internals were melting and after that the plate just stayed cold the entire time. This surprised me because i only had it on low heat
I bet the smoke is paper masking tape sticking the insulation down inside the hotplate part. It's a common problem with cheap chinese reflow soldering ovens.
dmt Handmade interesting. Makes sense.
I know this is old but do you know if this can heat low? I need something that can maintain about 60c, they always say the max temp but it's hard to find cheap things that say they start from 0, everything for cooking starts at like 200c
Hi. Did you ever finding a suitable hotplate? I'm in a similar situation (sometimes needing to maintain as low as 38C/100F) but haven't found minimums listed (except in some customer reviews where the plates start at 93C/200F).
@@llkg9 yes I bought this one above, I don't know the exact temperature as I'm just going of the specifications of the material I'm heating haha but I think you'll be fine with this one, I think it starts "heating" below ambient, so any heating level works if that makes sense, because it doesn't have any readout oor markings on the knob and it isn't instant like a flame, it does get a bit hard to judge whether you've got it set to the right temp though, you might think it's low enough but it just keeps rising, in my actual using it, it can definitely at least maintain handleable temperature if you set it right , whatever that is (around 40?), I can't vouch for lower but I think it would, it's surprisingly nice quality too, I'd recommend it.
the fumes were probably some oil residue from manufacturing.
I second this. I have had similar fumes happen when using a brand new heat gun I bought. Pretty sure it's not uncommon.
In all honesty for the price it seems to be a decent deal I appreciate you posting the review those manual grammar and Spelling mistakes are called Chinglish ! As it’s Chinas interpretation of English I’ve heard that it’s some computer Program they use to Convert Chinese to English and many things get twisted about because of the Dynamics of the two languages ? I beleiv\e I heard that from \a Cousin of m\ine who is fluent in Chinese and is American who sells To Chinese Companies
What is the time required to reach 100 C?
Hey, an update from me.
I've bought this product and it broke the first time I've used it.
thankfully, I filmed it all - from the unboxing untill the minute it broke. So I would probably get a full refund.
The video is now being uploaded to my channel. It's nothing interesting, just proof that what I'm saying really happened. after the smoke it stop working completely.
Benja shoot. That sucks. Good on you for getting it on video so you have something to show for the return. These things are cheap but so far haven’t had problems with mine. I’m sure that not all are made to the same standards though. Well I’ll make another video of the SH3 when that comes in and you can check that out.
it does not have an auto thermostat? so you cant make it heat a solution to a certain temp? means you have to stand next to it and check temps all the time? oh no. Id never buy one without an thermostat.
Mine is heating up while the heater is off any idea how to fix ?
same with me and the Stirrer not working also😭
This is because these companies have no quality control departments anymore! They just thrive on greed and quantity and never quality! So sad as we are not made of money, and some of us literally sacrifice certain basic needs to get our chemistry equipment and we wait impatiently for them to get to us only to find that either the goods we waited for are malfunctioning, glassware broken do to their shipping department not giving a shit and just packing the 2 500 ml flasks in a bag and shipping it ( happened to me so many times! ) the days of getting decent equipment at a reasonable price are all but over! Now we have to spend a lot more money and even then keep fingers crossed that everything is ok! I feel all you fellow amateur and students who are strapped for cash, pain!!!😢 take care my brothers! Keep the faith!
can i goes on 50 degrees?? cuz mine only activated at 110 degree
What do you mean?
CAN I USE THIS AS A DOORSTOP?
Huh?
Manufacturer recommends waiting a couple months, until it's ready for the trash bin.
Thx👍👍👍
Hi, some hotplates have numbers on their temperature knob, can you please tell what temperature each number show?
There Is a thermometer
You could have told us how hot it gets. You told us RPM.
And the minimum temp it can maintain too. Even in product listings, it's as if minimum hotplate temp is top secret info. 🙄
Imo this hot plate was trash does not hold consistent temp & can not even boil water .
please help me is that plate bivolt?
Hi, thank you for the review. You mentioned that you are using the stirrer for perfumery, I have interest in perfumery as well. My question is, is it able to totally dilute absolute to carrier oil? Do you have any experience about this matter? Thank you very much. Your reply is much appreciated :)
Hi Riztica! Thanks for your comment. I haven't used a carrier oil for perfume making. Perfumer's alcohol is almost 100% ethanol, which I make myself from fermenting sugar. In the sugar wash video, I have detailed this process, but I calculated it is considerably cheaper to make yourself. That said it's not too expensive. I also just enjoy making stuff myself. I don't own any absolutes myself but I do have some tinctures that are solid and mix well when heated. If you haven't checked them out already, there's a great company called perfumer's apprentice where I buy essential oils I cannot extract myself. I use the hotplate primarily to boil organic matter to get the oils. I hope that answers your question and points you in the right direction. I have another video called Bay Rum Perfume where I show some of the oils I purchased from the perfumer's apprentice. Let me know how your journey goes with perfumery!
When you say dilute absolute I’m confused what you mean by this, do you mean completely dissolve, most things that have a hard time dissolving in a solution it often helps to add more liquid as in more oil or water to dissolve any solids and heating it up will just help that go faster but you should only need to heat it up to 70degrees C to speed it up maybe 80 90 but going past 100 you run the risk of it becoming solid again when it cools down, this way you should know how much oil or liquid you need
This good for liters? Any problems??
Can I use this in making lip balm? Thank you!
Depends on how to make lip balm. I’ve never tried. Does that require heating because if so this might be appropriate.
The Bio Major yes it does because you need to melt the wax.. i want to buy this but i am afraid it can’t mix oils and waxes 😭
@@TheHappyNoona The magnetic stirrer could most likely mix them once they were melted. You could drop it in afterward. But as far as stirring, this is probably your best bet besides doing it by hand as the heat can be maintained simultaneously. But I don’t know much about the process.
The Bio Major thank you you’re a big help!
@@TheHappyNoona no problem!
hey there :)
any problems with it so far? any updates?
thanks for the review
No problems so far. I've only tested it at the time of making the video. I'm waiting on the rest of my distillation set up to arrive before I test it out again which should be in the next couple weeks. : ) Feel free to subscribe as I'll have more content coming and will make mention of how everything works once it's all set up!
How about now
Curious, was this a 1000ml capactiy model? Also where did u find that thermometer?
Derk Nizotts do you mean, will it fit a 1000mL beaker? If that’s your question, the size of the actual plate would barely fit one. I actually just got a 1000mL beaker and I’ve since ordered the SH3 model to accommodate it. The SH3 model has a 7”x7” plate compared to this SH2 model with its 4.7”x4.7”. So, although this would suffice for most stuff I think, my bigger one that arrives this Wed, will allow me to use much bigger flasks and beakers. I’m really into distilling essential oils too so having the ability to heat a 2000mL flask allows me to process much more oil at once. I got the thermometer off eBay as well for $4.40 from corale49. There are several measurement capacities available but the one I chose was -30 to 100C. The nice thing about glass thermometers is that you can use them with acidic reactions as there’s no metal to interact with. I bet by now though someone’s come up with a glass coated digital thermometer though.
@@thebiomajor5750 Thanks, Im very new to all this and dont wanna invest in junk or insufficient pieces.
@@derknizotts9162 You bet man. I'm with you on that. I've got a limited budget and don't like wasting money. Haha
I need to keep this at least 24 hours on, with the heater, can it do it or will it break?
Marcelo Maldonado haven’t tried that. Ive had it running for several hours though without a problem.
We are going to try that, so, i ll comment you, by the moment the magentic stirrer would be 8 hours
we had exactly the same one and it lasted 20 minutes then the hot plate gave up. we sent it back.
Hello. How many the price of this hot plate
Hello sir ...we are manufacturer of hot plates and much more product.. you can visit us at www.metwiz.in
Is this good for vortexing water?
Can it stir without heating?
Yes, it can stir without heating. : )
@@thebiomajor5750 did u try it?
@@thebiomajor5750 Can you tell me how long can it run? Does it support continous operation? If yes or no, then how long?
Does the thermometer come with the item ?
No
Hey bro, Im about to buy it. Do you recommend it still? Thank youu
Gonzlo Carrera I got rid of the SH2 awhile ago and upgraded to the bigger SH3. I have another video comparing the two. It depends on what you’re doing. What’s your application?
The Bio Major Want to make some experiments I’ve been watching about Bioplastics made with casein, ammonia and formaldehyde and others with starch and chitosan. So nothing very big, at the moment for the starch have been using the stove but would like to improve my method.
Gonzlo Carrera Cool! The bigger hot plate is useful if you want to make larger quantities of stuff, like I ended up wanting to distill more ethanol since it was quite a process so having a bigger hot plate made the batches worth doing but this small one will still get hot, it just doesn’t fit large flasks, say 3000mL. But if you’re working with smaller amounts of reagents, you shouldn’t have a problem. Really though check out my other video comparing the sizes since I have actual dimensions in that one.

My one couldn’t go over 60C and it took 1h30m to even get there
Yeah, you take a risk when you buy stuff from China. So far mine has worked through multiple distillations no problem. But sorry about that.
I sending it back and I’m gonna buy something else maybe a heating mantle and I appreciate you reading and responding to my comment.
@@demoror5585 Yeah, good luck! Hopefully you find something that works well.
@@thebiomajor5750 how long did it take to boil the 75ml u had in the beaker during the test ?
2:45 Serial Number '02'.....BWAHAHAHAHA!!
D@mn! So, not a serial number, but a code for which kid gets beaten when the units malfunction? 🤔
Wo0o0w👌🏻👌🏻👌🏻 great
Bro i don't need the unboxing part
I do
Relevancy is proportional to the quality of your delivery driver 😂
This will not cool down when you turn the knob down. Safety hazard!
No hot plate automatically cools down when you turn it off.. it’s like an electric stove. Turning it off stops supplying heat but it will still be hot for awhile
