Abstract
The centrifuge rotor is formed with a central chamber and two peripheral annular chambers concentric therewith; an annular bag including ring-shaped compartments, made of flexible material, and with communicating ducts are placed into the three chambers, the central chamber additionally being big enough to accommodate a holder for treatment liquid and for the reception of treated biological fluid, after centrifuging and treatment; valves, which may be centrifugally or otherwise operated, control flow between the central bag compartment in the central chamber of treatment liquid to the intermediate bag compartment in the intermediate chamber, and flow from the intermediate compartment of used treatment fluid to the outer peripheral compartment. A dimensionally stable, bulged, disk-shaped body is located in the compartments to assure that the bag retains its shape.
