Abstract
An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure () releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (). The bowl and portions of single use structure rotate about an axis (). A stationary inlet feed tube (), a centrate discharge tube () and a concentrate discharge tube () extend along the axis of the rotating single use structure. A centrate centripetal pump () is in fluid connection with the centrate discharge tube. A concentrate centripetal pump () is in fluid connection with the concentrate discharge tube. A controller () operates responsive to sensors () in respective centrate and concentrate discharge lines (), to control flow rates of a concentrate pump () and a centrate pump () to produce output flows of cell concentrate and generally cell free centrate.
