摘要

labware device closures and venting methods for labware device opening. a closure (1, 100, 150) for a labware device (20). the labware device (20) defines an inner chamber (25) having at least one aperture (92). the closure (10, 100, 150) includes a closure body (12, 102) configured to be mounted on the labware device (20) and in fluid communication with the aperture (92). a vent valve (14, 122) is mounted for movement relative to the closure body (12, 122) is mounted for movement relative to the closure body (12, 102). vent valve (14, 122) with closure body (12, 102) defines a space (72, 120) that defines a path between closure body (12, 102) and vent valve (14) 122) for exchanging gases between the inner chamber (25) and the outside of the labware device (20). a filter (50) is positioned within the space (72, 120) and is configured to filter contaminants from the gas entering the inner chamber (25) through the pathway.
