crimp top cap

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.

Crimp Top Cap is made of PTFE/silicone pad and aluminum cap with holes. This kind of Cap is usually made of silver aluminum with different colors of Septa. When used in Headspace Vial, it must be matched with Hand Crimper and Decrimper produced by Aijiren.

The 20mm aluminum crimp cap seal and sample vial ensure that the proper seal is made for this demanding application. 20mm crimp aluminum cap is often used with hand crimper and decrimper. Aijiren provides 20mm Hand Crimper and Decrimper. For details, please contact the sales manager.
