An enzyme immunoassay device comprises a disk having a thin flexible membrane applied to one side thereof, the membrane defining a conduit and a plurality of reagent reservoirs. The reservoirs are isolated from one another or from the conduit by frangible seals. An assay tube having an assay reagent bonded to the inner wall thereof is attached to the exit end of the conduit. Means are provided for injecting a test sample into the conduit for flowing thereof through the assay tube. Means are also provided for forcing the contents of each reservoir through the conduit and assay tube in the desired order by causing the rupture of each frangible seal sequentially.

A device for performing chemical and immunochemical assays, comprising: a disk having a thin flexible membrane applied to one side thereof, the membrane coacting with the disk to form a circumferentially disposed conduit having entrance and exit ends and also a plurality of circumferentially disposed reagent reservoirs, the reservoirs being isolated from one another or from the conduit by frangible seals, the frangible seals being arranged to define the desired flow of reagents through the conduit; at least one assay tube having entrance and exit ends, the entrance end being attached to the exit end of the conduit, the assay tube having an assay reagent bonded to the inner wall thereof; test sample injection means for flowing test sample through the assay tube; and means for forcing the contents of each reservoir through the conduit and the assay tube in the desired order by causing the rupture of each frangible seal sequentially, said means preventing back flow of reagent in the conduit.
