Abstract
A cover effective to releasably seal a multiwell container, such as a microtitration plate, is disclosed. The cover contains a pad, fashioned from a flexible polymer sheet, and a plurality of resiliently compressible ridges formed on the sheet. The ridges are deformable, such that application of pressure applied to the cover is effective to form a fluid-tight seal between the pad and the well openings. The ridges extend from the pad sufficiently to break the seal upon release of the pressure.
