Description of Septa and Cap for Snap Vial
The material of Hawach septa and cap for snap vial are high-quality polypropylene with precise manufacturing tolerances and aligned in a controlled environment. The color of caps we can provide black, blue, and clear and other colors accordingly to the client’s request. The material of the septa is the highest quality and purest silicone rubber and finest PTFE film. We utilize proprietary laminating/ bonding and conditioning technology to easily achieve needle piercing.
The snap caps are an extension of the crimp cap sealing method. The principle is to use septa and cap sleeved on the rim of the empty sample vials to form a seal by squeezing the septa between the glass and the stretched plastic cap. The tension of the plastic cap is caused by its attempt to restore its original size. The tension of the plastic cap can form a seal between the glass, the bottle septa, and the cap. Unlike the crimp cap, the plastic snap cap does not need any tool that can be covered.
