Caps, Snap Top, with 0.04" thick, White Silicone Rubber / Natural PTFE Pre-Slit Septa, fitted in smooth, polyethylene, Light Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. BASIK Brand. 1000/CS.
Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining dependable autosampler performance.
The 9502C‑E‑35B‑M BASIK Snap Caps offer a cost‑effective solution with pre‑slit septa designed to reduce needle penetration resistance. This makes them especially suitable for systems such as Waters® Alliance and Acquity instruments, where smooth needle entry improves injection consistency and reduces stress on autosampler hardware.
The natural (undyed) PTFE layer provides high chemical inertness without added colorants, helping minimize extractables and support clean analytical results. The silicone backing ensures reliable sealing while accommodating multiple injections in routine workflows.
The smooth light blue polyethylene cap allows quick application and removal, making these caps ideal for high‑throughput laboratories focused on efficiency and cost control.
