Abstract

A centrifugal separator for separation of a cell culture mixture includes a stationary frame, a rotatable assembly and a drive unit for rotating the rotatable assembly relative the frame around a vertical axis of rotation. The rotatable assembly includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged to rotate around an axis of rotation. The rotor casing includes a mechanically hermetically sealed inlet and first and second mechanically hermetically sealed liquid outlets. The second mechanically hermetically sealed outlet is arranged at an axial end of the rotor casing opposite and arranged so that a separated cell phase is discharged at the rotational axis. The rotatable assembly includes an exchangeable separation insert and a rotatable member.
