Vortex mixer
A vortex mixer (also known as a test tube shaker) is a small shaking device for everyday laboratory use, especially in biological and biochemical laboratories . Solutions that are in reaction vessels (e.g. Eppendorf cups , Erlenmeyer flasks , microtiter plates ) can be mixed thoroughly with this device. To do this, the reaction vessel is pressed onto the shaker attachment, a rubber recess on top of the device. Depending on the setting of the vortex, it begins to mix the reaction mixture by vibrating. Usual speed ranges reach up to 2500 min −1 . In addition to the strength of the vibration, the operating mode can also be set: continuous operation or short-term operation. In short-term operation, the device is only operated when the rubber recess is pressed down. With most devices it is possible to use reaction tubes between 1.5 ml and 50 ml in volume.
Other uses of the term
In some cases , manufacturers of static mixers in process engineering also refer to their products as vortex mixers.
