1. An assay support, generally planar and elongated in shape, and comprising a gripping section, a sample receiving well section, and a connecting section therebetween, each of said sections being aligned along a longitudinal axis;

  • said sample receiving well section comprising at least two spaced-apart receiving wells;

    each of said wells having an open end on a first face of said support, a concave inner surface extending concavely into said support, and a convex outer surface which projects convexly from an opposed face of said support;

    said convex outer surface of at least one of said wells provided with at least one stabilizing leg constructed and arranged to preclude rotation of said wells when resting on a flat surface;

    said assay support provided with a leveling projection extending from said opposed face so as to cooperate with said at least one stabilizing leg to maintain said support level when resting on a flat surface;

    said sample receiving section in the space between said wells comprises a dam means projecting from the first face of said support so as to preclude the flow of a liquid sample from one of said wells to another of said wells.
