ABSTRACT:
An improved centrifuge assembly comprising a channeled rotor assembly and a ring-like fluid container disposed in the channel, whereby the centrifugal separation effects in the fluid container are determined by the geometry of the channel in the rotor. The fluid container is preferably formed from semirigid plastic material in the form of a tube having a rectangular cross section and is considered a disposable item to be discarded after a single use. The rotor assembly preferably includes a removable filler piece or center piece formed from a single piece of material, such as rigid plastic, as by molding, dimensioned to form, with the wall of the centrifuge bowl, a circular channel having dimensions appropriate to receive the semirigid container, which is suitably bent and placed in the channel. Fluid connections are provided from each end of the container to an axially located multichannel rotating seal. The connections lie in a plurality of radial slots in the filler piece. Alternatively the entire assembly may be molded as a single entity, with a suitable channel and fluid line grooves being cast therein.
