ABSTRACT:
A flow-through coil planet centrifuge has variable rotation-revolution (r/R) speed ratios. The rotation and revolution are continuously adjustable by using separate variable-speed drive motors. A first embodiment employs rotating seals, whereas a second embodiment is without rotating seals. In the rotating seal embodiment the flow tubes are rotated synchronously with the column to avoid twisting; in the non-rotating seal embodiment a system of gearing and belts compensates for the rotation and revolution of the column relative to a stationary tube support to avoid twisting of the flow tubes.
