Abstract

An arrangement for chemical analysis of a small quantity of sample wherein a specimen of a small size is passed through a porous distribution first medium onto a reagent-containing second medium is disclosed. The reagent-containing second medium is a thin, flat, liquid-impervious medium. A reagent is encapsulated upon the second medium as a flat, liquid-phase surface. The first and second mediums are so arranged and disposed that when firmly pressed together, the encapsulated liquid reagent will be liberated and the specimen will be distributed through the first medium onto the liquid-phase liberated reagent where the subsequent reaction of the liquid-phase reagent and the specimen can then be identified by reading means.
