CENTRIFUGE SYSTEM FOR SEPARATING CELLS IN SUSPENSION

An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure (178, 240, 250) releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (172). The bowl and portions of single use structure rotate about an axis (174). A stationar...

Summary:An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure (178, 240, 250) releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (172). The bowl and portions of single use structure rotate about an axis (174). A stationary inlet feed tube (184), a centrate discharge tube (212) and a concentrate discharge tube (230) extend along the axis of the rotating single use structure. A centrate centripetal pump (208) is in fluid connection with the centrate discharge tube. A concentrate centripetal pump (216) is in fluid connection with the concentrate discharge tube. A controller (274) operates responsive to sensors (264, 270) in respective centrate and concentrate discharge lines (262, 268), to control flow rates of a concentrate pump (272) and a centrate pump (266) to produce output flows of cell concentrate and generally cell free centrate.
