2 mL Crimp/Snap Top Vials & Caps

Cap, snap, clear, preslit PTFE/silicone septa, 100/pk. These 11 mm clear snap caps come in 100/pks and include a press-fit septum made from blue PTFE/white silicone septum bi-layer. This combination is suited for a broad range of applications, however, is the main choices for HPLC applications where the sample is less volatile and/or were screw or crimp style vials are not appropriate. This particular version is used where additional sample prep steps involving pipetting is required in that the user can more easily remove and close the cap while holding the pipetter. The addition of the pre-slit to the septum makees it easier for the autosampler needle to pierce and reduces the chances of a vacuum forming inside the vial when sample extraction, however, there is a trade-off with a slightly weaker seal than when septum is not pre-slit. It is compatible wth all wide-opening 2 mL glass and polyproplene vials, 2 mL micro vials and 2 mL High Recovery Vials. These snap caps being press-fit (non-bonded) are the most sustainable cap option as the various components can be separated for easier disposal and recycling.
