Abstract

Eine Zentrifuge, insbesondere eine gleitdichtungsfreie Durchflußzentrifuge zum Zentrifugieren biologischer Fluide weist ein Gestell auf, an dem ein Rahmen (1) drehbar gelagert ist. An dem Drehrahmen (1) ist um dessen Achse eine Zentrifugenkammer (3) drehbar gelagert. Die Zentrifugenkammer (3) wird in der gleichen Drehrichtung wie der Rahmen (1) mit der doppelten Drehzahl angetrieben. Zur Übertragung des Drehmomentes auf die Zentrifugenkammer bzw. den Drehrahmen finden nach Art einer Kupplungsscheibe oder eines Zahnrades ausgebildete Kopplungselemente Verwendung, die mittels magnetischer Kräfte im Eingriff sind. Die Kraftübertragung erfolgt berührungslos und verschleißfrei. Eine Schmierung ist nicht erforderlich, wodurch auch die Ansammlung von Staub und Schmutz verringert wird. Darüber hinaus ist die Geräuschentwicklung gering.

Figure 00000001
A centrifuge, in particular a flow-through centrifuge free of mechanical seals for centrifuging biological fluids, has a frame on which a frame (1) is rotatably mounted. A centrifuge chamber (3) is rotatably mounted on the rotating frame (1) about its axis. The centrifuge chamber (3) is driven in the same direction as the frame (1) at twice the speed. To transmit the torque to the centrifuge chamber or the rotating frame, coupling elements designed in the manner of a clutch disc or a gearwheel are used, which are engaged by means of magnetic forces. The power transmission is contactless and wear-free. Lubrication is not required, which also reduces the accumulation of dust and dirt. In addition, the noise level is low.
