CUSTOM ITEM: 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. BULK PRICING.
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 septa increases the needle strike area, allowing easier alignment and smoother penetration during injections.
The 9502C‑E‑30KX 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 reliability in demanding analytical workflows.
Pre‑slit septa are commonly recommended for systems such as Waters® Alliance and Acquity. While the X‑slit enhances targeting and penetration, it offers slightly reduced resealing compared to single‑slit septa. The bonded PTFE/silicone septa provide excellent chemical resistance, while the black cap helps protect light‑sensitive samples and supports workflow organization.
