A method for measuring an agglutination reaction and the reaction.) found for use in the method

摘要

PURPOSE:To perform measurement of multiple reacting liquids with a small space simultaneously with high accuracy by using reacting vessels formed with at least one smooth recess on the side face. CONSTITUTION:Cylindrical reacting vessels 12-22''' which are spherical in the inside bottom parts 12A and are formed with a spherical recess 12B on the inner side face are arranged and are made rotatable about their perpendicular shafts by a motor 14 via belts 16-16'''. The reacting vessels 12-12''' are then rotated at high speeds to move the reacting liquids having accumulated on the bottom parts 12A to move into the recesses 12B and to accelerate cohesion reaction, after which the rotation is stopped and the reacting liquids in the recesses 12B are returned to the bottom parts 12A by gravity. The light of a light source 21 is irradiated to the reacting liquids having returned to the bottom parts 12A through a diffusion plate 22 and a holed reflecting mirror 24, and the reflected light thereof is led into a decision circuit 28 by way of a lens 25, photoelectric transducer 26, and a differential amplifier 27. Thereby, the presence or not of the cohesion reaction of the multiple reacting liquids and/or the degrees thereof can be simultaneously measured with high accuracy.
