CUSTOM ITEM: Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit Septa, fitted in smooth, polyethylene Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. Soft-Guard Brand. BULK PRICING.
Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance.
The 9502C‑E‑30B Soft‑Guard™ Snap Caps combine the benefits of pre‑slit septa with advanced Soft‑Guard™ silicone formulation. The pre‑slit design reduces needle penetration resistance, while the Soft‑Guard™ material improves resealing performance compared to standard septa. This helps extend instrument uptime, reduce missed injections, and improve overall data reliability.
Pre‑slit septa are commonly recommended for systems such as Waters® Alliance and Acquity instruments, where consistent needle entry and reduced resistance are critical. The bonded PTFE/silicone septa provide chemical resistance and sample protection across HPLC and LC‑MS workflows.
The smooth blue polyethylene cap allows for quick application and removal, making it well suited for routine and high‑throughput laboratory environments.
