ABSTRACT:
A biochemical test plate assembly is disclosed for use in both filter assays and fluid retention applications. The assembly comprises an upper template with a plurality of discrete apertures, a continuous microporous film underlying the upper template, a gasket underlying the microporous film with apertures matching those of the upper template, a lower template underlying the gasket with a similar array of apertures matching those of both the upper template and the gasket, each aperture terminating at its upper end in a flat boss, and a base plate having a central recess to define an enclosed chamber when the base plate and lower template are in contact, the base plate being designed to form an air-tight seal between it and the lower template.
