ABSTRACT:
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.
