Crimp Cap with Septa

Aijiren’s 20mm Crimp Cap with Septa is often used with Headspace Vials, and Headspace Vials is often used in gas chromatography. This type of chromatography requires a high degree of tightness for Vials, so Cap with Septa must also maintain a high degree of tightness. The production requirements for Aijiren are high, but Aijiren is an experienced company and is more skilled in the production of 20mm Crimp Cap with Septa.

The 20mm Crimp Neck Closures is sealed by squeezing the Septa between the edge of the Vial and the Crimpe Cap. Such a seal can prevent evaporation. The Crimp Neck is not as convenient as the Screw Neck, but the sealing is worse than the Screw Neck Closures. The center of the cover is 9.5mm. The center hole can be used for headspace automatic sampling. The standard specifications and neat and consistent production standards ensure the safety of sampling.

The 20mm Crimp Neck Closure produced by Aijiren is easy to seal, and it is very used with Headspace Vial. Because aluminum is a metal, it has high density and is not easy to breathe. Even with Center Hole, the matching Septa is a composite of 3mm thick Silicone and PTFE. Septa is 2mm thicker than ordinary Closures Septa. This thickness ensures the sealing of Closures. When the Crimp Cap is squeezed for sealing, the thickness of 3mm can just fill the gap between Cap and Vial after being squeezed.

Septa uses a composite of Silicone and PTFE. This composite process is Aijiren’s exclusive process and does not use adhesives for composite. This composite process ensures the flexibility and puncture of Septa. Since the Septa thickness of the 20mm Crimp Top Aluminum Closures is 3mm, it can meet the sealing requirement and bring a lot of trouble to the puncture of the automatic injection needle. The importance of composite craftsmanship is particularly prominent, which allows Aijiren’s unique craftsmanship to give customers a different experience.

There are two types of 20mm septa produced by Aijiren. They are made of silicone and PTFE. There are many colors, white, natural, white and blue, natural and yellow, natural and blue, and the style is two flat septa. Compound together. The other is a composite of PTFE and Butyl. Butyl has a harder material and is similar in color to PTFE, so a central hole pattern is made to distinguish the front and back sides.
