78-1 Magnetic Stirrer Hot Plate Magnetic Mixer 1000ml Lab Hot Plate with Magnetic Stirrer, 2400 RPM Magnetic Stir Plate with 4 Stir Bars and Support Stand, Max 158°F Hotplate Magnetic Stir

I have a background in chemistry, and I am very impressed with what I received for what I paid. I have used half a dozen brands & models of mag stirrers in my time, and this is my favorite I have ever worked with. Looks like a factory in the Soviet Union designed a magnetic stirring device in 1965 that just WORKED, and never bothered updating the design at all in the decades since (this unit probably actually is second-world import based on the instruction manual's stilted, translated English). Bear in mind that this is not a precision instrument. If you need your stirring to be at an EXACT speed, or if you need your heat to be at an EXACT temperature, this is not for you. It's a HOTplate, not a thermostat. Bear in mind that the heating function MAY be unsafe / a fire hazard if there's no liquid in a beaker on top of the plate to evaporatively cool it. Please use a digital thermometer to monitor the heating AT ALL TIMES. At any rate, if you need something that'll stir like a workhorse over a wide range of viscosities for days or weeks at a time if necessary, then this is perfect. Would buy again.

I bought this set to experiment with extracting gold from computer parts. It’s worked great since I got it and it’s fun to use. It’s also very easy to use and learn.

First off, this works. It gets hot and it has a strong spinning magnet. Thing is, it gets REAL hot eventually and there's no control other than turning off the heating element. If you need this at precision temps it's not for you. I use it to liquify and mix distillates, which it works wonders for. You need to pay attention and get it off when it's fluid, so you don't harm any actives though, bc again there's no way to know how hot it is at any given moment. It mixes very well and the speed controller also works nicely. This is something I need to use maybe every 3 months or so, and it's great for that.

The media could not be loaded. In the video i have stirrer running top speed, its a little unstable at that speed, might just be the size of my flask, i usually keep it at half speed, but you can see at the end, when i crank it up to top speed, it releases more gas from the solution, causing it to bubble through the water in the graduated cylinder.Used this many times, i monitor the heat and turn it off when it gets hot enough.the hot plate reads 220+ degrees F when at its hottest.the stirrer works great.would definitely recommend buying!

Easy to use and works well

Hot plate does not get very hot the mixing stick with the magnets work quite well ounce you figure out how to use it the directions are not to spacific.

Fantastic cheap mag stirrer. Never manually stir again! I use this for everything!Recommend buying a bar magnet with it.

This has no temp regulator. It’s hot, like burn your hand, hot. I know for sure it burns your pointer finger and middle finger really good because I did that. Also, I ran into hard times and this was an excellent way to make soup, and feel smart like I was a lab guy doing it. Cooks chicken noodle with rice pretty perfect. If you’re looking for a soup cooker that makes you smart, this is it.
