摘要:
A cap having a plurality of rib structures situated on an inner wall of the cap to facilitate the formation of air passageways as the cap is penetrated by a pipette tip. The air passageways aid in venting air from a fluid-holding vessel closed with the cap.
摘要:
A cap having a core structure dimensioned to receive a pipette therethrough. The cap includes two axially aligned frangible seals that are affixed to the core structure in a spaced-apart relationship. The frangible seals include a foil layer and are constructed so that air passageways are formed between the frangible seals and a pipette tip when the pipette tip penetrates the frangible seals. The cap optionally includes a filter interposed between the first and second frangible seals.
摘要:
A method for accessing the contents of a closed collection device having a cap and a fluid-holding vessel in fixed association. The method includes penetrating one or more materials of the cap with an air displacement pipette, thereby forming one or more passageways for venting air displaced from within the collection device, where the pipette includes structure for forming the one or more passageways. A fluid present in the vessel is drawn into the pipette before the pipette is removed from the collection device.

Methods for determining the presence of SARS-CoV in a test sample that include targeting the SARS-CoV 5′ leader sequence or the SARS-CoV 3′ terminal sequence.
摘要:
A method for obtaining the contents of a fluid-holding vessel having a cap secured to an open end thereof. The method includes penetrating a surface of the cap with a fluid transfer device and forming one or more air passageways between the penetrated surface of the cap and the fluid transfer device to allow air to be vented from the vessel. At least a portion of the contents of the vessel is then drawn into the fluid transfer device before the fluid transfer device is removed from the vessel.
摘要:
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.
摘要:
A cap for use in forming a sealed container with a fluid-holding vessel. The cap includes a downwardly tapered inner wall having a plurality of radially extending striations for improving the penetrability of the cap and for facilitating the formation of air passageways.
摘要:
An assembly that includes a specimen-containing vessel and a cap in sealing engagement. The assembly contains a specimen retrieval device having a handle, an end of which is positioned between a depending inner wall of the cap and a closed side wall of the vessel. The inner wall of the cap is adapted to be penetrated by a plastic pipette tip.
摘要:
A method for accessing the contents of an assembly that includes a cap in sealing engagement with a fluid-holding vessel. In the method, one or more rib structures on an outer surface of a plastic pipette tip engage the cap as the pipette tip penetrates the cap and enters the assembly. A fluid transfer apparatus operationally associated with the pipette tip draws a fluid from the assembly into the pipette tip. The fluid-holding pipette tip is then removed from the assembly.
