Abstract

A throughput centrifuge for the industrial production of proteins from human blood plasma, with a cylindrical centrifuge drum provided with several concentric chambers that communicate at the bottom and with the blood plasma or similar material being supplied to the central zone and a liquid phase continuously extracted from the outer zone. The drum accordingly accommodates plastic containers constituting concentric annular or annular-segmental chambers that communicate through at least one channel at the bottom, wherein the container or containers toward the axis that the drum rotates around have an inlet connection and the container or containers in the outer zone of the drum have an outlet channel at the top, and wherein the outer surfaces of the containers, of the communicating channel or channels, of the outlet channel or channels, and of the inlet connection or connections rest against the inner surfaces of the drum and against structures that can be inserted into and removed from the drum.
