Abstract
A centrifuge, especially a flow-through centrifuge free of rotating seals, for centrifuging biological fluids has a stand on which a frame (1) is rotatably mounted. A centrifuge chamber (3) is rotatably mounted on the rotating frame (1) to rotate about the axis of the latter. The centrifuge chamber (3) is driven in the same direction of rotation as the frame (1) but at twice the rotational speed. Coupling elements which are engaged by magnetic forces and are designed in the manner of a clutch disk or a gearwheel are used to transmit the torque to the centrifuge chamber or the rotating frame. Force is transmitted in a non-contact and wear-free manner. No lubrication is necessary, which also reduces the buildup of dust and dirt. In addition, there is little generation of noise.
