Abstract
Centrifugal processing apparatus in which a processing chamber is rotatably mounted with respect to a stationary base. An umbilical cable segment is fixed at one end substantially along the axis of the processing chamber at one side thereof, with the other end of the cable segment being attached substantially on the axis in rotationally locked engagement to the processing chamber. The cable segment comprises flexible tubing which defines a plurality of parallel longitudinal channels, with the cable segment having been stretched in the central portion thereof so that the central portion is narrower in cross-sectional dimensional area than the ends of the cable segment. In this manner, the channels remain large enough for effective connection of tubing to the walls defining the channels and the load of the umbilical tubing becomes substantially reduced.
