A cap assembly for use with a centrifuge container includes a stopper (plug) member to provide a fluid-tight seal of an open end of the container. The stopper member includes a channel therethrough. A lid receives the combination of a stopper fitted into the open end of the container. Depending portions on the underside of the lid press upon the stopper to ensure a reliable seal of the container. In addition, the depending portions are adapted to close off an opening of the channel when the lid and stopper are assembled. Removal of the lid opens the channel allowing air to flow into the container, and in this way any vacuum that develops in the container during a centrifugation run is released by such action.

[ I claim:] [1.] A cap assembly for a centrifuge container, comprising:a stopper member adapted to seal an open end of said container, said stopper member having opposed top and bottom surfaces and a closeable channel extending therethrough along a central axis thereof and having an upper orifice opening through said top surface and a lower orifice opening through said bottom surface; anda lid member adapted to removably engage said open end of said container, said lid member having opposed top and bottom surfaces, said bottom surface having downwardly depending rib members;portions of said rib members intersecting at said central axis and coextensive with said upper orifice opening;whereby, with said stopper member received in said open end of said container, engaging said lid member with said open end causes said downwardly depending rib members to press upon portions of said stopper member top surface and to cover said upper orifice opening, and whereby removal of said lid member separates said downwardly depending rib members from said stopper member top surface thereby uncovering said upper orifice opening.
