Abstract

An apparatus for separating a volume of composite liquid into at least a first component and a second component comprises a centrifuge having a rotor (32, 33, 34, 35). The rotor comprises a turntable (35) for supporting a separation bag (1) and a central compartment (34) for containing satellite bags connected to the separation bag (1). The central compartment is fitted with a support member (87) for supporting at least one satellite bag (2, 3) so that a liquid contained in the supported satellite bag (2, 3) drains from the supported satellite bag (2, 3) into the separation bag (1) under centrifugation forces when the rotor (32, 33, 34, 35) is set in rotation.
