Hot plates are NOT explosion proof or intrinsically safe. Do not use the high temperature setting to heat low boiling point liquids. Allow liquids to heat gradually on low or medium settings. Use heat resistant containers such as borosilicate glassware on hot plates.
Is hot plate dangerous?
Hot plates used in labs present many potential dangers, such as burns, fires, and electrical shock, which can cause injuries, significant disruption of lab operations, and loss of scientific data. The hot plate is a source of heat when on, and for some time after it has been turned off.
What precautions should always be taken when heating solvents on the hot plate?
Do not evaporate all of the solvent or otherwise heat a mixture to dryness on a hot plate-the glass container may crack unexpectedly. Use a medium to medium-high setting of the hot plate to heat liquids, including water. Do not use the high setting to heat low-boiling-point liquids.
