Scientific Industries still makes a version of this original vortex mixer.
A "'vortex mixer "', or vortexer, is a simple device used commonly in laboratories to mix small vials of liquid.
Both the vortex mixer and microplate mixer will be in the list .-- & trade; 23 : 12, 9 March 2009 ( UTC)
Vortex mixers are quite commonplace in analytical laboratory they may be used to mix the reagents of an assay or to mix an experimental sample and a dilutant.
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 ).
:: : The OP said the samples were in vials, not in microplates, hence a vortex mixer .-- talk 21 : 25, 9 March 2009 ( UTC)
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.
Most vortex mixers are designed with 2 or 4-plate formats, have variable speed settings ranging from 100 to 3, 200 rpm, and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece.
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.
