ABSTRACT:
Improved cytology centrifuge apparatus includes single or multiple well cell concentrators for being rotated by a centrifugal spinner. A rotor is removably supported by the spinner for rotation and is adapted to receive two or four cell concentrators. The rotor supports the cell concentrators in an unrestrained manner, thereby enhancing the ease of use and flexibility of the apparatus. Each cell concentrator includes a chamber having a top surface in which at least one fluid receiving aperture is disposed and a front surface in which at least one fluid expulsion aperture is disposed. A backing plate is provided with protruding top and bottom edges to vertically align a microscope slide with the chamber so that the fluid expulsion aperture is adjacent to a central portion of the slide. Retention clips secure the chamber to the backing plate with the slide sandwiched therebetween in horizontal alignment. The cell concentrator is shaped to rest stably on a planar surface in a tilted manner so that a fluid specimen contained therein is prevented from contacting the slide prior to centrifugation. The concentrator is also well suited for use as a staining chamber and the backing plate has a viewing aperture aligned with the fluid expulsion aperture to enable viewing of cells on the slide during a staining process.
