Slendor Magnetic Stirrer SH-2 Hot Plate Mixer Max 520℉ Lab Hotplate Stirrer 2000 RPM Stir Plate with Thermometer, Stir Bar and Support Stand

Did I ever like this hot plate? No. I'm used to working on Corning units in professional labs that have chemical resistance, precise temp control, 550°C max temp, powerful incremental stirring, and LCD display.This unit has none of these things, and is quite frustrating to use.To start, the knobs mean basically nothing. The heating element is only slightly warm until you crank it to max at which point its ripping hot. The stirring is only slightly more incremental, and quite shockingly weak as hot plates go. It also developed an issue early on where I had to fiddle with the knobs for like 3 minutes to get it to actually start heating at all.The hot plate surface has very minimal chemical resistance, and was permanently discolored by 2M HCl. It also happens to be designed in a way that's very difficult to clean/maintenance.AND all 4 little rubber feet melted from the heat of the hot plate itself within a month.Despite all that, this little unit lasted 7 whole months of very constant hobby use, which exceeded my initial expectations. It probably could have lasted longer but a beaker of boiling piranha solution spilled all over it.. which finally killed it for good.That said, I became quite fond of this little thing over the months along with all its annoying quirks, and I admit I'll miss it. At the end of the day the low cost helps with the barrier of entry into hobby chemistry, and it always (eventually) got the job done. I highly recommend this unit if you want to get into hobby chemistry, but aren't sure how long the hobby is going to last.

Fantastic for mixing with liquids, the included bar has problems pushing through powder.Making infused oils and butters is a breeze thanks to the included thermometer.The base remains cool to the touch even when hot plate is on so it can be used on any surface safely.All in all a great purchase for your lab / cooking needs!

Very well made and does what I need in my classroom. Safety is paramount.

Best value and fits in small spaces. Heats fast and stirs. Great style

The magnetic stirring component broke after a few times of using and the heating plate is not accurate. It’s either full heat or no heat regardless of setting. I have a non heated magnetic stirrer I’ve used for many years without issues so I think this is just faulty and it broke after the return timeframe.

Stirrer is great price was cheap. But I have yet to get it hotter then 98 Celsius which is a big bummer.

The H-2 Magnetic Stirrer works well. The temperature control is very precise (NOT just on or off as some reviewers have said). You must understand that the control knob sets the temperature of the hot plate, not the liquid in the flask. My process requires holding a liquid at 45c for two hours. It took some time but with a thermometer and a flask of water I found the spot to set the temperature control knob for 45c.

Buen producto calienta bien, mezcla bien.

Excelente producto

Everything came quickly and as described. Hot plate and magnetic stirrer work exactly as they should. Would definitely recommend to any beginner chemist students or teachers looking for something to teach with.

I use the stirring function all the time for mixing hot chocolate powder and it works perfectly well. Don't have to get another spoon dirty! You do have to make sure to line up the cup with the middle of the plate so the teflon stir bar catches and stirs with a nice whirlpool. The hot plate function actually heats quite hot but I don't really use it as much because I usually boil water on the stove.

Tiene un cuerpo metálico robusto y funciona a la perfección, el único detalle es que la superficie es ligerusimanete convexa, en la práctica ni siquiera se notaría, sólo cuando se coloca algo encima también convexo.

Excelente producto , cumple a cabalidad sus funciones. Precio adecuado.
