If you're stirring liquids in smaller quantities, or need to stir for an extended period of time, a magnetic stirrer may be just do the trick for you.
In this video, I demonstrate a countertop magnetic stirrer that I purchased on Amazon. This time of year, one of the most frequent liquids I prepare is 2 to 1 sugar water for my observation honey bee hive. Stirring in that much sugar into a relatively small quantity of purified water can take some time, so I thought I'd get a magnetic stirrer and let it just self-stir.
The only thing I didn't like about this particular stirrer is the length of the electrical cord, it's around 3' and I would have liked the standard 6' cord for the added placement convenience.
This unit is inexpensive and did a great job, I do recommend getting a larger stirring pellet.
Want to annoy your wife? Set up a beaker to stir your coffee or hot chocolate for that perfect "blend" with no sugar at the bottom ;)
Thanks for watching as always!

I want this to make the perfect choccy milk
They make mugs that use a portable version of this tech! I use it to make hot chocolate
Exactly 😂
@@shawncouch2243 what are they called can you post a name
We use these all the time in labs when dissolving crystals for buffers or when making media to grow bacteria or yeast in
That's a really good use 👍
I just want it to make whirlpools in general :P
Thank you, Fred and happy holidays sir.
You are welcome Tom and the same to you!
Those are handy, for myself when I need to stir harder to dissolve powder I actually bought a Hamilton beach shake mixer and that does a great job and it comes with the stainless steel cup to mix it. Great demo thanks for sharing.
Thanks, I don't personally like all the noise from blenders, mixers and even the handheld smoothie makers. Some mixes do better and end up with more dissolved solids after a lengthy stir cycle. Lots of options depending on the desired end result. After the initial stir, this is silent running and I really like that.
Frederick Dunn somehow i can understand that you’re a probably a quiet person given how soft spoken you are also. Not a bad thing at all and I assumed that’s why you preferred the magnetic method version a typical rotary blending method. Personal choice and having different ways are a good thing and I actually may try the magnetic method myself just for the heck of it.
My search for the perfect mixing system continues . . . :)
I went with a sh2 and sh3 for oil and sugar binding. Hope they get here soon its that time.
i recommend add more water so its not wiggling, what do u think? Wew
Excellent
Thanks doctor
What is the maximum viscosity and density
Just ordered one
Thank you 🙏.
If we reverse the polarity do we get a reverse direction?
Regards.
DC or AC depends
I never knew these existed! OMG...now I'm thinking of what I can use them for in my kitchen...BWAAAAHAHAHA THANKS Mr. Dunn! :D
I'm way ahead of you, I have a hot chocolate mixing right now and my wife is a "tad annoyed" by all the fuss :) BUT, I had one earlier and can say that having all the chocolate powder completely smoothed away is an entirely new experience... mmmmmmm..... BUT, as someone else mentioned, I wish I'd picked up one with a hot-plate built in.
@@FrederickDunn nice sir
Why is your voice so relaxing? lmao
I got one for shellac and whatever else. Looking forward to trying it. For the price, i figured why not. And it’s fun. Lol
What's shellac
great video.. just a quistion.. does this stirrer works also with a 3 a 4 cm magnet?? or is the best size magnet 1,5 cm ..
thank you so much 😊👍
Yes, it will work with those sizes.
@@FrederickDunn Thank you sir!!.. i did order a 2cm and 2,5 cm ..so i can test them in a 2 liter jar !! have a nice day 😊👍
THANKS
Could I mix 2 component epoxy resin with it? It's really thick
Hi Carmen, I personally would not do that as you have to clean the stirring capsule and it just may be too thick for effective mixing to occur.
What are the benefits to this method of making 2:1, vs mixing it on a stove top? I came across these on Amazon while browsing around, and now debating if they're worth it for making simple syrups and molecular mixology
Stove top is fine... this isn't necessary, it's a want not a need in my case :)
Frederick Dunn Thanks! That's what I assumed, although one with a hot plate would come in handy for me at work to set a 2:1 demerara syrup and not need to constantly watch...hmm 🤔
Definitely, if I were getting another one, it would have temperature controls and would be able to handle the larger stirrers. Definitely don't want the temp to go too high. Let me know what you end up getting and how it works for you! I just may have to go shopping again :)
Thanks for sharing...Would you mind trying a 32 ounce Ball Canning jar with straight water...I am interested to see if the magnet is strong enough to still spin the water through the thicker glass...Thanks
Some Ball jars have a raised center at the bottom, it's not as good as the thin glass beakers. The stirrer will flip off to the side often.
@@FrederickDunn Yeah...that is what I was wondering...need to get a flask or beaker instead...
@@FrederickDunn some,
Use the glass from a French press
I use these for cultivating yeast. Cheapest i could find in uk was £90 so i made one for about £12. Great things to have tho.
Wow, that's expensive! I could definitely see it used for yeast and even those who have to keep salt brine moving for brine shrimp production, better than an air bubbler in my opinion :)
@@FrederickDunn you breed shrimp with a magnetic stirrer?
These are cool
You know it!
What length is the stirring pellet that comes with it and what size would you recommending to upgrade to?
Hi Sam, thanks for that question, but unfortunately, I have a collection of stirrers and just added the one with them and can't recall which one was included. I "think" it was about an inch and a half in length? I tried to add a 3" stirrer and it completely failed, so you have to keep the length under 2" if you want it to remain in the center.
Usually it comes with a 30x7mm
Nice
anyone know if this cheap of one will work for something like a tiz solution with PG?
no idea
Can be used for so many things - great demo....
Thanks Daniel, I have to agree!
in all things - stirred not shaken is my motto
ya, what did 007 know anyway (';')
@@danielweston9188 facts
three years later it still works? or approximately how much time work before you need another one?
Still working fine.
Anyone know if it would work for dielectric grease? Will it stir?
nope
I know this is an old vid... Buuuttt... I'm concerned it doesn't have an "off" button? Do I have to unplug it? Or does it click/turn off on the low setting?
You turn it off with the speed control knob.
@@FrederickDunn thanks for the response!
You're welcome!
Would this work for stirring nail polish?
nope
uhhh is it bad i want one to stir my tea bc im just that lazy
Nope, the more complicated you can make a simple task, the better in my opinion!
I also have this one, it's great for amateur lab work
Does a stirrer structure the water ?
If you keep the water at 4°C/39°F while stirring for at least 20 minutes yes...
Hi frederick how goes your bees you look like experienced can you tell which bees can fight varroa without threat
Hi Max Bees, my bees are doing extremely well. This year, in particular, I wanted to make videos showing varroa in worker brood or drone cells and the hygienic behavior of my bees causes them to remove varroa destructor mites before I can locate and photograph them. I also have an observation hive/colony that is completely untreated and they also are too effective at removing varroa for me to capture the evidence. I do monitor them and they are handling varroa without intervention. Look into BeeWeaver and learn more about the genetics they are working with, these are the bees I've used for over 10 years.
is that buckfast or italians
I use the Weaver Queens... I've already ordered three more for 2018, Not the Buckfast or Italians- those require treatment to help with varroa. The Weaver Lines do not require treatment- shop.beeweaver.com/bees/queens
woww that is nice to hear with 4,9mm cell or
5.28 mm cell size
The reviews on amazon for this particular one arent great. Anyone use this model?
Hmmm, it's still working fine for me :)
Could you use this for something already blended but separates in glass bottle or plastic bottle?
If it's a bottle, remember that you still have to drop the stirrer inside and be able to get it back out. But if it has a flat bottom, it should work.
Thank you for your reply, I was just thinking for nail polish or glue that separates.
Is this good for mixing epoxy with hardener ?
I would not think so, it really can't handle anything that thickens.
@@FrederickDunn if you heat up both .... it becomes like water
Could this be used to stir epoxy
Not strong enough.
Hi! Have you tried foaming milk with it ?
No, we have a milk-frother for that :)
Frederick Dunn but is it possible anyway? ) I would like to use it in competition routine on barista championship) if it works
It really wouldn't get enough air introduced for frothing in my opinion. Best of luck with your competition!
can you mix in plastic container?
Yes.
Does it make the water magnetized?.
nope
This stirrer is with heating or not?
not heating
Would this effectively blend protein powder and milk together?
Thanks for asking, I don't it could handle that mix.
@@FrederickDunn thank you for the quick reply!
Can this be used for mixing Epoxy?
And do you have to use a glass container for the pellet to work?
No, it wouldn't be good for epoxy.
Never saw it in secondary school lab
can it mix warm honey ?
Nope, it can't handle that.
Would this device be strong enough to support ice?
no
@@FrederickDunn even with a set of stronger magnets at a steady paced amp?
@@gretabuccellato9094 There are lots of tutorials that show how to build your own, I think I'd make a beefier version for what you're wanting to do.
@@FrederickDunn Thanks!
@@FrederickDunn I'll let you know how it turns out.
Will this froth milk?
no
Surprised you didnt buy one with a heating element in it.
What?! (';') now you tell me.... !!!
I wonder what would happen if you replaced that magnetic stirrer underneath the beaker for an induction stove.
no idea
@@FrederickDunn Thanks for the reply. I've been waiting impatiently for two years. I suppose I'll have to try it myself. 😀
Would this be cool at a bar let me know folks
how u remove it tho?
There's a long magnetic stick you use to fish it back out ☺
400 series stainless steel rod.
I try to blending Honey, but it didn't work
Why would you be blending honey?
If only the shape was like a boats rotor it will create more drag
There are diferent size and shapes stirr bars for all your stirring needs😁
why don't you leave some honey for the bees to eat? great product all the same.
Hi Brian, if you've watched my honey bee videos, that's exactly what I do... each of my colonies has circa 80-100 lbs of honey in frames for wintering. Thanks for your comment and for watching.
اخوي اشرح بالعربي الوضع داج يمي 💔😭
أعتذر ، لست متأكدا من كيفية التواصل باللغة العربية. أتمنى لكم كل التوفيق.
Weird question but could this beat an egg?
great question and the answer is no.
The tablet keeps going sideways
Inllabs dont last beyond 90 days continuous operation. The speed control fails...
Mine still works. Did you send it back?
@@FrederickDunn I had 4 units fail the same way. I operate them for 21 days straight at a time. They all fail into the 5th use. Appx 90 days.
IMHO
B o b o
Get a more powerfull magnet so it won't be thrown to the sides at higher speeds
You generally use higher volumes of liquid for the higher spinning speed
Try highly flocculating (WPL-002 for example) yeast at end of a slurry/pitch development :) Its an out-of-box (in my case) working cheap ($30 bucks) china product. Up to 4L with vortex of air down to the stir bar for me in convex beaker. Recommend it highly for 30 clams. Not a top notch product at all, basic stuff.
30 clams?
Very Inexpensive? $30 is a lot to me :')
imma use this for choccy milk
ok then
This thing is useless for stirring VG I've returned it lol
you used it in e liquid?it doesn t work on mixing the vg/pg ? i was thinking on using it on it
helith teixeira not that cheap one no
gonna search some other one ,need one to blend my e liquids
helith teixeira all this one is is a small cheap motor with terrible magnets and no torque. Mine got red hot trying to stir 20pg 70vg and could not actually stir it properly.
Jimmy06 i see,i found this one on eBay,maybe it will work better m.ebay.com/itm/1L-Home-Laboratory-Magnetic-Stirrer-Mixer-Apparatus-Hotplate-Heating-Plate-220V/302709393225?epid=15016669184&hash=item467ae2c749:g:HtgAAOSwafta1~Sw
We're not fancy like you, but we're way fancier than you.
ok then
And now they make mugs that do this for $20
OOOhhh nice!
