International ClassB01L 011/00AbstractA multi-well plate which prevents cross-contamination of samples through the use of a resilient gasket which covers a majority of the top of the plate and is compressed by a lid having a clamp assembly. It thus provides a sealing assembly for arrays of containers of any size or shape. The gaskets may be unitary sheets with or without an array of openings corresponding to the well openings or may consist of discrete single well gaskets. A multi-tube array is also provided which can be sealed without the need of a gasket or tight-fitting caps. A multi-well plate is also disclosed in which samples can be gas-equilibrated without the risk of microbial contamination.Other References
