Agglutination analyzing vessel

DETAILED DESCRIPTION An object of the invention, therefore, is to provide an agglutination analyzing vessel which can eliminate the above mentioned drawbacks which have been encountered with the prior art techniques and which can form stable, clear, and precise agglutination patterns of particles, for example, test blood corpuscles by an immunological agglutination reaction irrespective of the strength of agglutination.
Another object of the invention is to provide an agglutination analyzing vessel which can form stable, clear, and precise agglutination patterns even when the settling down particles are red blood corpuscles having a weak agglutinating property.
A feature of the invention is the provision in an agglutination analyzing vessel which can make a test liquid containing particles in a stationary state and cause the particles to settle down so as to form agglutination patterns on the base surface of the vessel and which can effect an immunological analysis, of the improvement in which said base surface is provided on at least one portion thereof with an inclined surface which is provided on at least one portion thereof with a plurality of engravings regularly arranged and forming a stable substrate for said settling down particles on said inclined base surface.
Further features and objects of the invention will be fully understood from the following detailed description with reference to the accompanying drawings, wherein:
