Abstract
A cytocentrifugation device of the type disclosed by the copending Stokes-Quirante U.S. application Ser. No. 07/788,310 (U.S. Pat. No. 5,252,228 on Oct. 12, 1993) is improved by the provision of elongate, rounded projections on and protruding from the clamping face of the delivery conduit flange at the delivery end of such conduit and the flattening of the otherwise rounded and flange contacting end faces of the clamping arms. Further improvements include a floating mounting for the clamping arms so as to ensure even clamping of the annular area of the absorption pad marginal to the absorption pad opening confronting the cell deposition area of the microscope slide that is otherwise covered by the absorption pad, and the provision for positively, properly aligning the several items to be clamped together during operation of the cytocentrifuge apparatus.
