Abstract

The invention relates to an improved multiwell cluster plate. The wells of the plate each have an upper chamber and a lower chamber separated by a microporous membrane. Adjacent to each well is a corresponding access port. The access port is a separate opening in the tip surface of the plate which provides direct access to the lower chamber of the corresponding well, without disturbing the upper chamber or the membrane
