ABSTRACT:
A device for mixing, homogenization, resuspension, disintegration, disruption, or centrifugation of media placed in test tubes, including: a rotor having a replaceable closure; a driver having a substantially vertical shaft; a sleeve having a spiral groove and a bush moveable along the sleeve, moving the rotor up and down; and a stationary ring with extended teeth faced toward the rotor. When the rotor is in its lower position the tubes engage the teeth and receive strikes which induce vigorous motion and effective mixing of media inside the tube. When the rotor is in its upper position the tubes are disengaged with the teeth and rotation of the rotor provides centrifugation of the media.
