A magnetic stirrer or magnetic mixer is a laboratory machine that employs a revolving magnetic field to reason a stir bar (also called "flea") absorbed in a liquid to spin very rapidly, thus stirring it. The revolving field may be created either by a rotating magnet or a set of stationary electromagnets, placed below the vessel with the liquid. Magnetic stirrers often take in a hot plate or some other means for heating the liquid.

A vortex mixer has an electric motor which turns a pipe facing upwards. This pipe is attached to a small rubber bowl where one can put a beaker of liquid to be mixed up. The rubber bowl turns quickly and create a vortex or a twisting flow within any water which is placed on it and is therefore mixed up. Most vortex mixers have control which let the user control how fast or slow they desire the mixer to turn and can also set it to revolve continuously for a certain length of time.
