<p>A closure (10, 100, 150) for a labware device (20). The labware device (20) defines an interior chamber (25) having at least one opening (92). The closure (10, 100, 150) includes a closure body (12, 102) configured to be mounted to the labware device (20) and in fluid communication with the opening (92). A vent valve (14, 122) is mounted for movement relative to the closure body (12, 102). The vent valve (14, 122), with the closure body (12, 102), defines a space (72, 120) that defines a path between the closure body (12, 102) and the vent valve (14, 122) for gas exchange between the interior chamber (25) and the exterior of the labware device (20). A filter (50) is positioned within the space (72, 120) and is configured to filter contaminants from gas entering the interior chamber (25) via the path.</p> |
