The present invention relates to a centrifuge rotor with a rotor body and a receptacle arranged centrally therein for receiving a drive head of a drive shaft of a centrifuge which can be rotated about an axis of rotation (R), and sample receptacles for accommodating a plurality of sample containers. A holding crown is arranged on a top side (O) of the rotor body facing away from an insertion side (E) of the drive head, said holding crown having an annular base body, which encloses a central opening, and prongs extending upward away from the top side (O), wherein the holding crown is arranged in such a way that the axis of rotation (R) runs through the central opening. The present invention further relates to a holding crown for use with a centrifuge rotor and having an annular base body enclosing a central opening and prongs emanating from the base body and extending upward, wherein the prongs are offset at least in the region of their free ends by a spacing (A) from an inner edge of the base body. The present invention further relates to a holding crown arrangement comprising the holding crown, and a centrifuge comprising the centrifuge rotor, the holding crown or the holding crown arrangement.

A method for separating a biological suspension includes dispensing a liquid suspension comprised of cells or microorganisms from a bioreactor or fermenter into a sterile compartment of a first bag assembly, the first bag assembly including a collapsible bag having of one or more sheets of flexible film. The compartment of the first bag assembly is sealed closed. The first bag assembly, either with or without a manifold fluid coupled therewith, is then rotated, such as by using a centrifuge, so that the liquid suspension separates within the compartment into a pellet comprised of the cells or microorganisms and a liquid supernatant.
