Can kitchen hot plates be used in chemistry labs?
They're a lot cheaper and they don't seem much different.

The reason why a lab hotplate is built the way it is, is for spills. The lab hot plate will not catch the drips like a household hot plate will. The lab hot plates I am familiar with are flat ceramic topped with no lip to catch anything. The household hot plate is usually a spiral heating element with a drip pan below. The only other difference is temperature controls. The lab plate usually has a calibrated dial that the household plate does not have. My home hotplate has three settings, low, medium and high. My lab hotplate (from a previous life as a chemical analyst) has a range of 100 to 400 degrees F and is accurate, (based on external thermometer measurements) to +/- 10 degrees F.
