PNR™

Sample Preparation Systems
 

PNR™, an acronym for Pierce-able and Re-sealable, is the name of COPAN unique patent pending invention of pierce-able and re-sealable screw caps of various sizes designed to be applied to specimen collection tubes. The top of the cap is covered with a pierce-able metallic foil, which protects the Duck Bill valve until the moment of use. The PNR™ cap revolutionizes specimen management by eliminating time consuming de-capping, re-capping and repetitive stress injuries. Also, the re-sealable feature ensures that specimens are immediately reclosed, eliminating the need to do it manually and avoiding potential contamination from tubes being open for prolonged periods of time.

PNR™ caps are available in piercable (and not resealable) format only.

  • Enable easy entry and exit by automatic pipetting system.

    The PNR™ cap, when used with an automatic pipettor, enables automatic opening, sampling and reclosing.
    Automatically and quickly reseals after sampling and it is leakproof.

    Load and walk away

    No need to remove and replace tube caps during processing.
    It reduces risk of repetitive stress disorder by eliminating the need to cap and recap samples.

    How does a PNR™ Cap work?
      • PNR™ caps, when used with automatic pipettors, enable automatic opening, sampling and re-closing* of tubes: just load and walk away, no need to remove and replace tube caps during processing
      • The automatic pipettor breaks through the foil cap seal and pierces the membrane opening the Duck Bill valve
      • Then, the automatic pipettor enters the tube. The pressure must equilibrate immediately; otherwise, the volume uptake is hindered or exaggerated by the pressure. This rapid equalization is achieved by the unique design of the valve creating multiple micro-vents.
      • The liquid is taken up and the automatic pipettor exits
      • The PNR™ cap’s membrane valve reconstitutes within a few seconds to make the tube leakproof*.

    * not applicable in case of piercable caps, where the duck bill valve is not present.
