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.

Abstract: Hose arrangement for a seal-less centrifuge having a soft inner layer and a hard outer layer and is formed by means of coextrusion.

Abstract: The invention relates to a centrifuge comprising a separation chamber, with which a duct is permanently connected, a main rotor, on which the separation chamber is able to be bearinged in a relatively rotatable manner with respect to it, by means of a bearing arrangement, and a guide means on the main rotor for guiding the duct from the middle lower part of the separation chamber into a part at a higher level than the centrifuge. In order to be able to introduce the separation chamber into the main rotor in a simple and controlled manner the bearing arrangement has, within the main rotor, a part which is open or is able to be opened in a radial direction for the introduction of the duct into the main rotor.
