ABSTRACT:
An improved device for performing agglutination reactions is disclosed. The device has at least one chamber with a proximate zone and a distal zone in which chamber agglutination reactions can be performed. The improvement comprises utilization in the device of a layer of liquid absorbent material for controlling overall rate of liquid flow through the chamber. The layer of liquid absorbent material is selectively impregnated with a substance to form an impregnated region and a non-impregnated region wherein the non-impregnated region is liquid absorbent and the impregnated region is liquid-occlusive. A portion of the non-impregnated region is positioned within the distal zone of the chamber so that the non-impregnated region is in liquid communication with that zone.
