ABSTRACT:
A canister for holding a solid phase support for use in a biospecific binding assay is disclosed. The canister consists of a receptacle and cap, both shaped to mate with each other in a snug fit, the cap having a central opening spanned by the solid phase in the form of a thin porous disk. The central opening is surrounded by a raised surface which forms a protective wall avoiding inadvertent contact of the disk by the user or surrounding objects. The cap and receptacle are constructed so as to provide a vent when the parts are joined, providing gravitational flow of a test sample across the porous disk into the interior of the receptacle.
