Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The silicone/PTFE septa combination offers dependable sealing and chemical resistance for routine analytical workflows.
The 9502C‑E‑35C‑M BASIK Snap Caps feature 0.04" thick natural PTFE pre‑slit septa bonded to silicone rubber, enabling easier needle penetration and improved injection consistency. Pre‑slit septa are commonly recommended for Waters® Alliance and Acquity systems, where reduced penetration resistance supports reliable autosampler performance.
Natural PTFE contains no color pigments, minimizing the risk of extractables and background interference in sensitive analyses. As part of the BASIK product line, these caps provide a cost‑effective solution for high‑volume laboratories. The natural transparent cap supports easy visibility, sample identification, and efficient workflow organization.
