A device is disclosed for collecting a liquid which has been separated into at least first and second fractions according to the densities of such fractions. The device comprises a stationary transferring element and a housing for said stationary transferring element. The housing is rotatable about an axis of rotation for the device and the housing and stationary transferring element provide a fluid communication space therebetween for fluid communication between the housing and stationary transferring element. The housing includes first and second outlet passages for passing said first and second separated fractions through the housing to first and second points in the fluid communication space, and the transferring element includes first and second outlet channels for passing the first and second separated fractions from the first and second points in fluid communication space through the transferring element. The first point of communication in the fluid communication space is positioned radially outwardly from the axis of rotation of the device with respect to said second point in said fluid communication space so that when the housing is rotating the separation of the first and second fractions in the fluid communication space is maintained at least partially by centrifugal force.

Transferring means for use in a device for separating liquids

A rotatable rigid disc for separating a liquid into fractions according to the densities of such fractions is disclosed. The rigid disc includes an inlet for the liquid to be separated; at least two outlets for the separated liquid fractions; and a separation chamber in the form of an elongated, curved conduit. The conduit is fluidically connected to the inlet and the outlets, the outlets are positioned on the disc radially outwardly with respect to the inlet, and the outlets are positioned along the elongated, curved conduit so as to provide a separate collection location for each outlet and so that the densest fraction is separated by the outlet nearest to the inlet and the least dense fraction is separated by the outlet most distal from the inlet.
