Abstract:
     An entrainment device for a centrifugal rotor, which is rotatable about a central rotational axis (R), having a number of entrainment members (11;12) arranged in said space (4) for entrainment of entering liquid in the rotation of the centrifugal rotor. The entrainment device comprises a first component (14), which surrounds the rotational axis (R) and has at least one first projection (16), which has a radial extension, and a second component (15), which surrounds the rotational axis (R) and has at least a second projection (17), which also has a radial extension. The second component (15) is axially insertable in said central space (4) to a position, in which said second projection (17) is present adjacent to said first projection (16). When the entrainment devices (11; 12) are in place in the central space (4), a locking member (18; 20) is applicable in releasable engagement with said projection (16; 17) so that the second component (15) is prevented from moving axially relative the first component (14).
