11mm crimp neck vial cap, silicone/PTFE septa
The crimp cover of the vials is made of aluminum for crimping and sealing; plastic (polyethylene, polypropylene or phenolic resin) for non-crimping and sealing. The cap gasket is a septum material that is pierced by a syringe needle to extract a sample from the vial. The cap liner sheet has various configurations and is also made of various materials.
Crimp closures N11 are also universally suitable with regard to autosampler compatibility.
11mm aluminum seals are compatible with Aijiren Vials, wide opening and standard opening 11.6x32mm aluminum seal vials
Seals and septa are pre-assembled
The improved GC septa with aluminum seals offers multiple injection capabilities with zero extractables. The septa also offers better re-sealing than standard red rubber seals.
