ABSTRACT:
A centrifuge rotor is described which facilitates the preparation of cell dispersions on microscope slides. The rotor is bowl-like in configuration and defines plural peripheral regions adapted to receive the slides and a removable sample chamber associated with each slide. Each chamber has an outlet adpated to contact its slide. A sample, containing blood cells, for example, may be placed in a chamber and the cells centrifugally sedimented against the slide associated therewith. Excess or unwanted fluid is removed from the chamber by applying a vacuum through a vacuum line and hollow drive shaft. Leaf springs maintain each chamber in position and the vacuum line in fluid contact with the chamber. The vacuum line conecting each chamber cooperates with its leaf spring such that if a chamber is missing, the leaf spring closes the vacuum line.
