Abstract

A multi-well plate which prevents cross-contamination of specimens through the use of a resilient gasket which covers a majority of the top of the plate and is compressed by a lid. It thus provides a sealing assembly for arrays of containers of any size or shape. A multi-well plate of modular construction is also disclosed in which resilient gaskets prevent cross-contamination of samples. The gaskets may be unitary sheets with or without an array of openings corresponding to the well openings or may consist of discrete single-lell gaskets. A multi-well plate in which the wells have conical ends is also provided.
