ABSTRACT:
A bio cell cleaning rotor assembled in a centrifuge. The rotor includes a plurality of test tube holders for holing a plurality of test tubes. The holders are pivotally movably supported to a rotor body so that the test tube holders are moved toward a horizontal direction upon application of centrifugal force. A cleaning liquid distributor is positioned above the rotor and is rotatable together with the rotor for distributing even amount of cleaning liquid to the plurality of test tubes. The distributor includes a disc like upper segment and a disc like lower segment in opposition thereto. The upper and lower distribution segments are molded products and have radially outer side flat sections in intimate contact with each other. A plurality of radial grooves are formed in at least one of the flat sections. The radial grooves serving as cleaning liquid distribution nozzles each having radially outer end open toward each opening of each test tube.
