Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining reliable autosampler performance. The pre‑slit septa design reduces needle resistance during injection, improving alignment and supporting consistent results.
The 9502C‑30CY Snap Caps are one of the most popular and widely used snap cap configurations on the market, with over 25 years of proven performance in laboratory environments. The silicone rubber / PTFE septa provide strong chemical resistance while maintaining resealing capability for multiple injections across HPLC and LC‑MS workflows.
Pre‑slit septa are commonly recommended for Waters® Alliance instruments, where consistent needle entry and reduced penetration force are critical. The yellow polyethylene cap supports clear visual identification and efficient color‑coding for organized, high‑throughput workflows.
