Customer Reviews for Magnetic Stirrer with Heating Plate 85-2 Hotplate mixer 110V Digital Display

Great value and prompt delivery

Arrived on time as expected was very simple to figure out and use.

Great buy

I'm using this for decarboxylation and mixingFor the price this is exactly what you need.Temp controller and thermocouple rod comes with for control from 1F to 210F

you'll probably want to buy a good set of clamps for the post, but this is mostly a lot bang for the buck. could get hotter, but it boiled methanol okay. easy to set the thermometer and the cable is long enough to get in the pot. spins like a champ. I bought another one

This unit does get hot, for only 200W, it gets it right up there, and holds at the temp you set. Unfortunately if you tirn the heat off to cool, it turns off the temp readout, but you can flip it back on to check it. The platform gets very hot and so does the whole top, hot enough to melt the temp sensor wire if its too close.

Out of control do not buy FIRE HAZARD

Good price and it does the job.

Read a review that said there was no auto temp control. Appearantly they didnt read manual. You can in fact set the tem range and it will hold within that range

This is a great value, if the limits of what it can do work for you. It can only heat something up to about a liter, and can only be used with non-flammable fluids (no alcohol), it will heat slowly initially, it can not be used to boil liquids or heat above 100C (212F). The name, as awkward a translation as it is, says what it is meant to do: keep something at a constant temperature while stirring it. Since there is no shielding or seal of the heating element, there is an exposed under plate, you must avoiding spilling liquids or solutions that might burn or foul the elements. It does maintain a fairly constant temperature, but is not calibrated well: it was off by about 3.3 degrees (held at 33.3 when set for 30). You need to calibrate the PID for parameters, but the manual is incomplete and poorly written. I found a Chinese manual for the PID controller on line that provides better detail.
