Abstract
In order to free a liquid form a substance dispersed therein and having a larger density than the liquid a centrifuge rotor is used having a stack of conical separation discs. Elongated spacing members (11a, 11b) in the spaces between the separation discs are formed such that the liquid flow in the disc interspaces is conducted in a certain way. Thus, the main part of the liquid is conducted in flow paths (12a, 12b), each of which has a direction with one radial component and one component turned against the rotational direction of the rotor.
