The present invention reveals an apparatus for mechanically finger vortexing microcentrifuge tubes. The apparatus is made of a box; a tube-holding rack having a frame, where the top of a microcentrifuge tube is held in a pivotal position; a base plate having a plurality of upright ribs, where the ribs cause a pull-and-release action either directly or indirectly on a microcentrifuge tube; a wheel, where the wheel is connected to an armature and where the armature is connected to the base plate; and a motor with a shaft, where the shaft is connected to the wheel. In the operation of the apparatus, the motor and the shaft impart a circular motion to the wheel and the armature transposes the circular motion of the motor-wheel to a reciprocating motion on the base plate. The reciprocating motion of the base plate causes the ribs to mix the contents of the microcentrifuge tubes. |
