An automated system for preparing a plurality of cytological specimens from a plurality of fluid samples in vials includes an apparatus for collecting a monolayer of cells from each sample and transferring the cells to a microscope slide for fixing, staining, and inspection. The system includes a first loading station for receiving the sample vials, a second loading station for receiving consumables such as filter membranes, a slide dispenser, and an unloading area for removing completed specimen slides. To maintain one-to-one correlation between the samples and specimens produced therefrom, the system includes a subsystem for identifying each sample and permanently marking each slide with corresponding indicia prior to transferring the specimen thereto.

Method and apparatus for preparing cytological specimens

A device for collecting particles, such as human cells, from a fluid sample, and for transferring the collected particles to a receiver, such as a glass microscope slide, provides substantially exact replication of the spatial distribution of the cells on the collection device. The device supports a surface-collecting filter on a tubular rim, with a precise degree of flatness, and fastens the filter in place at a mounting shoulder recessed below the rim. Distortions of the mounting shoulder or of the filter at the mounting shoulder, caused by securing the filter to the shoulder, are confined to the shoulder structure, and do not detract from the desired precision flatness of the filter and rim structure.
