Abstract
A plate for use in an immunological analysis on the basis of agglutination reaction of particles, has formed therein a number of reaction vessels 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 are formed in the bottom surface to allow formation of a stable basic layer of settled particles, which basic layer can assure the formation of clear and precise particle patterns on the bottom surface.
