Centrifuge and swing-out rotor

Abstract

A centrifuge includes a swing rotor. Rotor arms of the swing rotor have recesses into which hangers of the swing rotor at least partially swing in a swung-out state. As a result, the centrifuge container and thus also the centrifuges are more compact, because the swinging-out requires less space. An inertial mass of the swing rotor is reduced due to the recesses provided therein, whereby energy consumption, primarily when starting the centrifuge, is significantly reduced.

Description

technical field [0001] The present disclosure relates to swinging bucket centrifuges and rotors for swinging bucket centrifuges. Background technique [0002] Centrifuge rotors are used in centrifuges, especially laboratory centrifuges, to separate components of a sample centrifuged therein based on sample density. Use higher spin speeds to achieve high separation rates. A laboratory centrifuge is a centrifuge in which the rotor preferably runs at a speed of at least 3000 revolutions per minute, preferably at least 10000 revolutions per minute, in particular at least 15000 revolutions per minute and is usually placed on a bench. In order to place them on the bench, they may have a form factor of less than 1m x 1m x 1m; thus they have limited space. Preferably, the depth of the device is limited to a maximum of 70 cm. [0003] Such centrifuges are used in fields such as medicine, pharmacy, biology and chemistry. [0004] In most cases, centrifugation of the sample at a ce...

Problems solved by technology

[0014] The disadvantage of such oscillating rotors is that they occupy a relatively large space due to the oscillating movement of the suspension that occurs during the outswing, so that the dimensions of the centrifuge for centrifugation must be relatively large compared to fixed-angle rotors
