Particle agglutination analysing plate.

摘要

A plate (1,2) for use in an immunological analysis on the basis of agglutination reaction of particles, has formed therein a number of reaction vessels (3) each having a conical bottom surface. The plate is formed by molding of chemically resistive acrylic resins. Each vessel has an inclined bottom surface and a plurality of concentric protrusions or depressions (5) are formed in the bottom surface to form a stable basic layer of settled particles, which basic layer can assure the formation of clear and precise particle patterns on the bottom surface.
