ABSTRACT:
A rotor for separation and collection of specimen particles carried by a liquid buffer by continuous centrifugal elutriation, whereby the interior of the rotor itself is employed as a separation chamber. This separation chamber is shaped such that the circumferential cross-sectional area thereof continuously increases from the outer to the inner periphery in a specific manner, so that centrifugal elutriation is accomplished by pumping the liquid buffer from positions at the outer periphery of the separation chamber towards the inner periphery. A transparent cover can be employed to cover the separation chamber, so that the separated material becomes directly visible as a peripheral ring, without the need to employ a stroboflash lamp, and in addition it is possible to separate large amounts of material by a single centrifuging operation.
