ABSTRACT:
An apparatus for conducting chemical assays features a coiled soft plastic tube as a reaction chamber. Along the length of the plastic tubing is a slit therein through which a needle-like member of a travelling dispenser injects samples to be analyzed. The injected samples may react with a reactant previously deposited in the interior of the plastic tube. The apparatus is applicable to carrying out radioimmunoassays.
