ABSTRACT:
The invention relates to a centrifugation enclosure (1) made of rigid plastic that comprises a member (1b) adapted to engage with the driving organ of a centrifugation machine (M) and a communication member (5) between the enclosure (1) and the outside, made of rigid plastic and comprising un first duct (5a) extending therethrough for supplying said enclosure (1) as well as two ducts (5b,5c) extending therethrough for discharging the separated components. A holder (3) made of rigid plastic and having a network of channels (4a,4b,4c) formed therein connects the ducts (5a,5b,5c), respectively, to supply (P1) and reception (P2,P3) tanks, with side sealing members (6) of said channel network (4a,4b,4c). The ends of the ducts (5a,5b,5c) are adjacent to the respective ends of the channels (4a,4b,4c), and the ends of the ducts (5a,5b,5c) have surfaces mating with the end surfaces of the respective channels (4a,4b,4c), said mating surfaces being connected to one another.
