Abstract
A centrifuge with an associated container system in the form of cassettes for separation and treatment of blood or blood components has been developed. The centrifuge includes a rotor having a central compartment in the form of a tubular shaft cavity extending concentrically with the axis of rotation of the rotor and an annular separation compartment which is arranged around the cavity at the upper part thereof. A first container system is arranged in the rotor, for washing of blood cells, includes a round bag and two or more flexible secondary containers connected thereto, one of which contains a treatment liquid and a tubular sleeve adapted to the shaft cavity of the rotor. The secondary containers are arranged in the sleeve to rest against each other and the round bag is mounted on a projecting flange at the upper part of the sleeve.
