Hotplates and hotplate stirrers are benchtop laboratory tools that are used to heat evenly and mix various types of liquids and solutions. Conventional hotplates are used for heating only, while combination stirring hot plates are able to simultaneously heat and mix. Infrared hotplates are an energy-efficient alternative to conventional and combination stirring hotplates. Hotplate accessories such as temperature probes, external digital displays, and heating blocks can be combined with compatible hotplates.
