Abstract: Improved method for the measurement of substance comprising simultaneously measuring a plurality of specimens of a substance to be measured by enzyme immunoassay. The process comprises:a. reacting specimens and a material which will be specifically combined with the substance to be measured and which has been made in the solid phase;b. separating the reaction mixture in step (a) into the solid phase and the liquid phase;c. reacting the solid phase with an enzyme-labelled product of a material which will be specifically combined with the substance to be measured;d. separating the reaction mixture in the step (c) into the solid phase and the liquid phase;e. reacting the solid phase or the liquid phase with a substrate for the enzyme in the step (c); andf. measuring the optical density of the reaction mixture.

Abstract: This washing apparatus comprises holding a pipe assembly by means of a holding means. Said pipe assembly is consisted of a pouring pipe which acts to pour a wash liquid in micro wells of a container and a suction pipe which acts to suck said waste wash liquid from said micro wells. Said pipe assembly is formed of a dual-pipe consisting of a suction pipe and a pouring pipe disposed inside said suction pipe. The forward end opening portions of said both pipes are located on the substantially same plane.
