2 mL Crimp/Snap Top Vials & Caps

Cap, snap, clear, PTFE/silicone/PTFE septa, 100/pk. These 11 mm clear snap caps come in 100/pks and include a press-fit septum made from red PTFE/white silicone/red PTFE septum tri-layer. This combination is suited for a broad range of applications, however, is the main choice 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 tri-layer septum is especially useful when sample needs to be secured for longterm storage and/or septum is pierced multiple times and exposed to corrosive organic solvents such as chloroform. 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.
