Abstract

See full text

An apparatus for simultaneously processing a plural number of samples, each of the samples including a fluid containing particulate matter. The apparatus is useful in cytology to collect a uniform monolayer of cells from a biological fluid. Each of a plural number of processing assemblies (corresponding to the plural number of samples) comprises a container, an agitator rotatable relative to the container for contacting and dispersing particulate matter in the fluid, a filter assembly including a filter for collecting particulate matter, and a pump for moving the fluid through the filter. Each container is supported on a separate container receiver, and each pump is engaged by a separate pump engagement. A rotary driver effects relative rotation of the agitators and their respective containers simultaneously to mix the samples in the containers.
