The invention relates to a centrifuge provided with a blood bag system having an upper and lower outlet for separation of blood constituents, containing a rotor which can be driven in a rotative manner about a hub, wherein at least one conventional whole blood bag equipped with an upper outlet and with a lower outlet can be positioned vertically in this blood bag, while the whole blood bag can be arranged on the rotor in such a way that one outlet of the whole blood bag is bent in a radial direction, and the opposite outlet of the whole blood bag is bent in the other radial direction, so that the entire whole blood bag and the outlets thereof adopt an approximately Z- or S-shaped form in its functional position. In this case it is preferred that the upper outlet of the whole blood bag lie radially toward the interior and the lower outlet of the whole blood bag lie radially toward the exterior of the whole blood bag. The whole blood bag is held in an insert, and the insert is in its turn held by an approximately sector-shaped cartridge, wherein a plurality of such cartridges is uniformly distributed by being arranged around the circumference of the rotor. One advantage of the centrifuge is that conventional blood bags can be used and recovery of individual blood constituents (plasma, erythrocytes, buffycoat) can be achieved with a significantly higher degree of efficiency and functionality, and with a high degree of purity.
