Abstract
Removed 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. 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. Each cell concentrator includes a chamber having at least one fluid receiving aperture and at least one fluid expulsion aperture. The chamber is secured to a backing plate by a fastening mechanism, with the slide sandwiched therebetween. In one embodiment, the chamber is hinged to the backing plate. Also described is a bibulous pad interposed between the chamber and the slide in order to absorb excess sample fluid.
