Hot plate

A hot plate is a portable self-contained tabletop small appliance fitted with (usually) one heating element, either electric or sometimes a gas burner. Electric hot plates tend to be more common, as they're safer to operate.


Hot plates consist of a flat body, which houses the internal circuitry, electric switches and the heating element. The heating element is inside the circular dome, while the temperature is controlled through buttons and voltage regulators.


Hot plates can be bought from most kitchen and electronic stores.

Lab hot plates, simple or also capable of magnetic stirring can be purchased from most lab suppliers.

DIY hot plate

Lab hot plates can be easily made at home by connecting a heating element to an insulated plate. To add magnetic stirring, you can simply glue a series of magnets on a fan motor and place it below the heating element.

Safety and handling

Hot plates do not glow when hot, and since they don't cool immediately after being turned off, you can burn yourself seriously if you accidentally touch them with your bare unprotected hand.
