Abstract
An apparatus for use in depositing and staining cytological material on a microscope slide has an elongated hollow tube, a base member, at least one flange, and a base plate. The base member is attached to the bottom end of the tube and projects outwardly from the tube perpendicular to the longitudinal axis of the tube. At least one flange is connected to the base member and outwardly-extends from the base member perpendicular to the longitudinal axis of the tube. The base member has a recessed area configured to receive the microscope slide, and slots configured and dimensioned to receive the flange. A passage in the base plate extends from each slot to releasably secure the respective flange when the tube is rotated. As designed, this apparatus advantageously allows individual staining of a slide, thereby preventing false-positive results due to floater cells which can translocate between slides in a common bath.
