Laboratory centrifuge |
(57) The present invention briefly concerns a centrifugal rotor for laboratory centrifuges,
comprising a disk (1) and a cover (10), whereby a ring-shaped carrier (5) of capillary
tubes (9) is attached to the bottom of the disk (1). The disk (1) has at its outer
periphery an axially projecting flange (3) which is inclined relative to the axis
of rotation of the centrifugal rotor, so that any liquid escaping out into the centrifugal
rotor is urged by the centrifugal force to the ring-shaped, circular edge (20) formed
between the flange (3) and the bottom (2, 17) of the disk (1). Preferably, the cover
has a peripherally outer portion with a step in the form of an axially extended portion
(13). which continues in a radially ring-shaped edge portion (14), the axially extended
portion (13) having a height greater than the thickness of the folded-back portion
(4) of the axially projecting flange of the disk (1) and a gasket ring positioned
thereon.
