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.
