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 sample delivery.
The 9502C‑30CR Snap Caps are one of the most popular and trusted snap cap designs on the market, with over 25 years of proven laboratory use. 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 red polyethylene cap supports efficient color‑coding and sample identification in high‑throughput analytical environments.
