Abstract
In a centrifuge rotor, the separation chamber (21) of which contains a set of conical separation discs (10), these are guided radially by means of guiding means (11) extending axially through the discs. At their ends, the guiding means (11) are fixed relative to the rotor body (1,2) in its periphery direction and radially. The rotor body has an upper part (1) and a lower part (2), which are held axially together at their peripheral portions. A distributor has a base portion (7) on which the separation discs (10) rest, and a neck portion (6) which extends centrally up through the disc set. The distributor is radially guided relative to the lower part and the upper part, respectively, of the rotor body. Cylindrical guiding surfaces (9) are present between the neck portion (6) and the upper rotor part (1) and, possibly, also between the base portion (7) and the lower rotor part (2).
