(54) DESCRIPTION OF THE INVENTION DEVICE AND METHOD OF IMMUNO ANALYSIS PROVISIONS.

(57) Summary Analysis carrier having a generally planar and oblong shape and comprising a gripping section, a sample receiving well section and a blind section therebetween, each of the sections being aligned along a longitudinal axis. The sample receiving well section comprises at least two receiving wells 1 spaced apart, each of said wells having an open end on a first surface of the carrier, a concave inner surface extending concave interior 1 said carrier and a convex outer surface which convexly projects from an opposite surface of the carrier. The convex outer surface of at least one of said wells is provided with at least one stabilizing leg adapted to exclude rotation of the wells when the carrier is on a flat surface. The analysis carrier is further provided with a horizontally extending projection projecting from said opposite surface and adapted to cooperate with said at least one stabilizing leg for maintaining the horizontal position of the carrier 1 when resting on a flat surface. The sample receiving section is also provided, in the space between said wells and protruding from the carrier surface, with a locking device adapted to exclude flow of a liquid sample from one of said wells to another. Also described are a plurality of releasably connected assay carriers of the type described above. Further described is a method for using the analysis carrier for performing one The sample receiving section is also provided, in the space between said wells and protruding from the carrier surface, with a locking device adapted to exclude flow of a liquid sample from one of said wells to another. Also described are a plurality of releasably connected assay carriers of the type described above. Further described is a method for using the analysis carrier for performing one The sample receiving section is also provided, in the space between said wells and protruding from the carrier surface, with a locking device adapted to exclude flow of a liquid sample from one of said wells to another.
