Additional Info:
Snap caps provide a quick, press‑fit sealing solution for autosampler workflows, eliminating the need for threading while maintaining reliable sealing performance.
The 9502C‑30CB snap caps are one of the most widely used and trusted 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 supporting consistent sampling, especially in systems such as Waters® Alliance.
The PTFE layer offers strong chemical resistance and protects sample integrity, while the silicone backing provides flexibility for reliable resealing. The smooth blue polyethylene cap ensures easy application and removal, making it ideal for routine and high‑throughput workflows.
