Additional Info:
Snap caps provide a fast, press‑fit sealing solution for autosampler workflows, eliminating the need for threading while maintaining reliable performance.
The 9502C‑30CB‑M snap caps are one of the most popular and widely used snap cap designs on the market, with over 25 years of proven performance. The pre‑slit silicone/PTFE septa allow easier needle penetration, reducing resistance during injection and improving consistency—especially beneficial for systems such as Waters® Alliance instruments.
The PTFE layer provides strong chemical resistance and helps maintain sample integrity, while the silicone backing supports resealing for multiple injections. The smooth blue polyethylene cap allows easy application and removal, making it well suited for high‑throughput laboratory environments.
