Abstract

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.
