Laboratory Shaker

They are the most used in laboratories and at the same time the safest, because they use stirring bars that can be disinfected. This type of mixer is made up of a plate with a magnet or a series of electromagnetics, arranged in a circular shape at the bottom, which create a rotating magnetic field that acts by means of an electric motor controlled by an electronic device.

The (magnetic) stir bar, normally covered with an inert film such as Teflon, is placed inside the container and the beaker or container is placed on top of the plate. Once started, the stirring bar begins to rotate, propelled by the electric motor that moves the magnets. The size and shape of the magnetic bar determine the effectiveness of the stirring process, considering a constant speed. Some models of magnetic stirrers also have a heating system – some reach up to 300ºC – to heat the samples at the same time as they are stirred.

Laboratory Shakers in operation

They are used to shake test tubes or the like in laboratories. This type of mixer is composed of an electric motor with the transmission shaft oriented vertically and attached to a piece of rubber or rubber in the shape of a cup, slightly eccentric, where the tube to be stirred rests. They also have suction cup feet at their base to prevent displacement. The stirring speed can be regulated. As the motor rotates, the rubber part oscillates rapidly in a circular motion, facilitating the agitation of the tube. There are different models of vortex agitators, for example, for a continuous speed or to work only when a weak pressure is applied to the rubber.
