Snap Top Caps with Septa

All materials are produced at 100,000 grade clean room. Passed ISO9001:2015 quality management system certification, RoHS compliance can also be provided.

The 11mm snap-top caps are made of high-quality polypropylene. The caps have a roll-edge or snap-on shape. The snap-top caps provide a secure seal that minimizes evaporation even for volatile samples. PTFE/silicone septa are the product of choice for most HPLC and GC applications where resealability and high purity are critical. Ideal for applications where ease of needle insertion is important. Silicone septa have strong re-sealing properties and can still maintain good sealing performance after multiple injections; PTFE is currently a material with good chemical conditions and can withstand strong acids and alkalis. After the two materials are combined, the bottle can be used for various laboratory purposes such as sealed sampling and chemical storage.

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.

Preassembled polypropylene snap-top closures with a 6mm center hole, including  PTFE/silicone septa. To use with 11mm snap-top vials. Snap caps provide a secure seal, minimizing evaporation even with volatile samples. 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.
