Abstract
Cytocentrifugation apparatus is improved by providing centrifuging devices with a plurality of liquid-receiving chambers arranged serially along and opening into an elongate conduit leading to and terminating within a filter-pad-holder so that a filter-pad-prewetting liquid can be passed along such conduit and into a liquid-flow opening of a filter pad held by such holder in advance of passage along said conduit and through such liquid-flow opening in the filter pad of a cell-carrying liquid sample during a centrifugation run of the apparatus. Retention of prewetting liquid in the filter pad around the sample liquid flow helps to prevent loss of cells to the filter pad. Various other structural modifications of the cytocentrifugation device and filter pads used therewith also help to prevent loss of cells to the filter pad.
