Flow system for centrifugal liquid processing apparatus

A disposable flow system for use in conjunction with a centrifugal cell processing apparatus of the type having

• a stationary base,
• a rotor drive assembly rotably mounted to the base for rotation along a predetermined axis,
• a rotor assembly including means for receiving at least one cell processing chamber, the rotor assembly being rotatably mounted with respect to said base for rotation along the axis
• guide means for causing rotation of an operatively engaged cable segment with the rotor drive assembly about the axis, and
• drive means for rotating the rotor assembly and the rotor drive assembly in the same direction with a speed ratio of 2:1,
• said flow system comprising, in combination:
• at least one cell processing chamber mounted on the rotor;
• a container for containing cells to be washed;
• a container for containing wash solution;
• means including a flexible umbilical cable segment having at least one passageway in communication with said processing chamber for selectively establishing flow communication with said cell and wash containers;
• and
• a leader assembly having a pouch portion containing said cell processing chamber, and a flexible cable portion extending from said pouch portion through said guide means for guiding said cell processing chamber through said guide means into position on said apparatus.
