ABSTRACT:
A self-contained assembly for assaying an analyte in a liquid sample. The pair of disc-like rotatable plates forming the assembly are relatively rotatable to align reagent reservoirs in one plate with a reaction well in the other plate, for sequential addition of multiple reagents, either in liquid or solid form, to the reaction well. In one embodiment, the reaction well includes solid-phase particles which can be transferred from the reaction well to spaced wells in the assembly by a combination of relative movement of the plate, and rotation of the entire assembly.
