Laboratory Magnetic Stirrer Or Magnetic Mixer

Much of the current magnetic stirrers rotate the magnets by means of an electric motor. This type of equipment is one of the simplest to prepare mixtures. Magnetic stirrers are silent and provide the possibility of stirring closed systems without the need for isolation, as in the case with mechanical agitators.

Because of their size, stir bars can be cleaned and sterilized more easily than other devices such as stirring rods. However, the limited size of the stir bars enables using this system only for volumes less than 4 L. In addition, viscous liquid or dense solutions are barely mixed using this method. In these cases, some kind of mechanical stirring is usually required.
