Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit (X Shape) Septa, fitted in smooth, polyethylene, Green Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. Soft-Guard Brand. 1000/CS.
Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The X‑shape pre‑slit design increases the target area for autosampler needles, allowing easier alignment and reduced resistance during penetration.
The 9502C‑E‑30GX‑M Soft‑Guard™ Snap Caps combine this X‑slit design with advanced Soft‑Guard™ silicone formulation, delivering easier penetration while maintaining improved resealing compared to standard septa. This helps extend instrument uptime, reduce missed injections, and improve consistency in high‑throughput workflows.
Pre‑slit septa are commonly recommended for systems such as Waters® Alliance and Acquity. While the X‑slit provides superior targeting and penetration, it offers slightly reduced resealing performance compared to single‑slit septa. The bonded PTFE/silicone septa ensure strong chemical resistance, while the green cap supports efficient color‑coding and sample organization.
