Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining dependable autosampler performance.
The 9502C‑E‑35B BASIK Snap Caps offer a cost‑effective option with pre‑slit septa to reduce needle penetration resistance. This design is commonly recommended for systems such as Waters® Alliance and Acquity instruments, where smooth and consistent needle entry improves injection reliability.
The natural (undyed) PTFE layer provides excellent chemical inertness without added colorants, helping minimize extractables and support clean analytical results. The silicone backing allows for consistent sealing and reliable performance during routine use.
The smooth light blue polyethylene cap enables fast application and removal, making these caps suitable for high‑throughput laboratories focused on efficiency and cost control.
