11mm Snap Top Caps with Septa for Supplier
11mm snap top vial cap with septa
Caps are made of high-quality polypropylene, Caps have the profile of a crimp or snap closure for compatibility with robotic autosamplers, Pre-assembled septa reduce the chance of contamination during sample preparation while saving sample preparation time in the lab.
Snap caps provide a secure seal, minimizing evaporation even with volatile samples, The audible click ensures that a secure seal has been formed and the cap is properly applied. Snap caps have septa pre-assembled, Snap caps are compatible with Aijiren Vials and other snap-ring style vials
Snap ring closures N11 should only be used in HPLC, as the punctual compacting pressure of the septum against the vial rim by the four pins in the cap does not achieve the same level of tightness as the evenly applied pressure through a screw thread or by crimping.
High-quality, pure silicone is laminated to PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures.
PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical. Works well for applications where ease of needle penetration is important.
