Abstract

A centrifugal apparatus, in particular a flow-through centrifugal apparatus for processing biological fluids in continuous fluid communication, has a flexible tube securely fixed to a rotatably processing chamber and a stationary terminal coaxially above said processing chamber, and being formed in a loop around the outer periphery of said processing chamber so as, in operation, to orbit said loop around said processing chamber at half the rotational speed thereof to avoid twisting or drilling of said tube. To guide said loop of tube in its orbital movement, a rotating frame is provided also rotating at half the speed of the processing chamber. The drive trains for said processing chamber and said rotating frame, respectively, each comprise an individual drive shaft each drivingly connected separate from the other to a drive motor. This avoids any necessity of reversal of rotational direction in the drive trains and allows for a compact and simple construction with a minimum of rotating masses.
