Abstract
Provided is a masking system of masks for use with multiwell plates such as microtiter plates to facilitate sample dispensing and assay accuracy, especially when dispensing more than one solution into the wells. One or more masks, adapted in size to fit snugly over a multiwell plate and the mask formed with openings each aligned with a subset of one or more wells of the plate beneath, aids the user in sample and/or reagent administration. Advantageously, the masks contain registration aids so that proper orientation with respect to the plate below is achieved; the registration aid may be a cut corner, registration peg or mark, or visual marking or stamping.
