Abstract
A cap which can form an essentially leak-proof seal with an open-ended vessel capable of receiving and holding fluid specimens or other materials for analysis. To minimize potentially contaminating contact between a fluid sample present in the vessel and humans or the environment, the present invention features a cap having a frangible seal which is penetrable by a plastic pipette tip or other fluid transfer device. The cap further includes a filter for limiting dissemination of an aerosol or bubbles once the frangible seal has been pierced. The filter is positioned between the frangible seal and a retaining structure. The retaining structure is positioned on the cap above the filter and may be used to contain the filter within the cap. The material of the retaining structure may be penetrable by a fluid transfer device.
