Scientific Industries still makes a version of this original vortex mixer.

Inside, a vortex mixer has an electric motor which turns a pipe facing upwards.

Vortex mixers are quite commonplace in bioscience laboratories.

A vortex mixer is small machine used in laboratories to mix small beakers of liquids.

Most vortex mixers have variable speed settings and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece.

Equipment such as the vortex mixer and vortex scrubber have been installed in pharmaceutical plant, offering benefits such as:

Vortex mixers are used in bioscience laboratories to mix two different chemicals for a desired effect or to dilute an acid or an alkali by mixing them with water.

She kissed Conor, who was now wearing the white lab coat she had found for him, but his attention was absorbed in holding a microfuge tube against a vortex mixer.

Most vortex mixers have controls which let the user control how fast or slow they want the mixer to turn and can also set it to turn continuously for a certain length of time.

The vortex mixer was invented by the Kraft brothers (Jack A. Kraft and Harold D. Kraft) while working for Scientific Industries (a laboratory equipment manufacturer).

In the simplest example of the method, an equal volume of beads are added to a cell or tissue suspension in a test tube and the sample is vigorously mixed on a common laboratory vortex mixer.

An alternative to the electric vortex mixer is the "finger vortex" technique in which a vortex is created manually by striking a test tube in a forward and downward motion with one's finger or thumb.

This generally takes longer and often results in inadequate suspension, although it may be suitable in some cases when a vortex mixer is unavailable or the forces involved in vortexing would damage the sample, but this technique is not recommended when caustic substances are involved.
