Abstract

A fluid receptacle is provided with a retainer on the inner surface thereof for confining at least the reactive portion of a coated insert matrix within the receptacle during inversion thereof. The insert has a configuration permitting fluid to be poured into the receptacle and decanted from the receptacle by inversion of the receptacle with the reactive portion of the insert confined therein. The various decanting, washing and measuring operations involved in an assay may therefore be performed while the insert remains confined within the original receptacle, eliminating the need for additional receptacles and for manual assembly or disassembly operations during the assay.
