Tabletop laboratory devices designed as an integral unit that combines a hot plate and a magnetic stirrer. These devices typically consist of a unit with a flat plate (e.g., made of aluminum or ceramic) on which the container of liquid to be heated and stirred is placed; the device also includes electrically powered heating coils to heat the plate and electromagnets to create a rotating magnetic field that spins a magnetic bar placed inside the liquid. Hot plate/stirrers are used mainly in clinical laboratories when simultaneous heating and stirring of solutions is needed.
