The Vortex Mixer features adjustable mixing speed control to deliver gentle agitation through to vigorous mixing whereby a
vortex forms within the vessel.
To change the mixing speed

decrease the speed.

The speed may be adjusted during mixing to achieve the desired level of mixing inside the vessel.
Note: The mixing action can be altered by changing the angle at which the vessel is held.
