Vortex mixers are mainly used to mix beakers or small vials of liquid. The device itself is straightforward, consisting of an electric motor with a vertical drive shaft.

The machinery is typically attached to a rubber cupped piece that is slightly off balance. Simple mixers handle from one to a few vials, while more complex multi-tube mixers can handle dozens of vials.

In a vortex mixer, the motor drives the rubber cup in a circular motion to create a vortex, or spiral flow, in a sample. The idea is to place what needs to be mixed, such as a test tube, into the rubber piece so that it will rotate as well.

Most vortex mixers have two or four plates and have several speeds, from a creeping 100 rpm to a vigorous 3,200 rpm, along with other programmable features. These can be set to run continuously or only when pressure is applied to the rubber cup.

Vortex mixers are most commonly found in bioscience laboratories. For instance, in the work of cell culture and microbiology laboratories, they are usually required to suspend cells which is a primary function of a vortex mixer.

In biochemical or analytical laboratories, vortex mixers also are commonly used to mix reagents or to blend a sample and a diluent.
