Rotor-Stator Homogenization

Rotor-stator homogenization uses a rotating metal shaft (the rotor) inside a stationary metal casing (the stator). The rotation of the rotor creates a suction effect which draws the sample into the space between the rotor and stator, in which it is subject to very high shear forces due to the an extreme change in velocity in the small space
