CUSTOM ITEM: Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit (X Shape) Septa, fitted in smooth, polyethylene, Yellow 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, improving alignment and reducing resistance during penetration.
The 9502C‑E‑30YX Soft‑Guard™ Snap Caps combine this X‑slit design with advanced Soft‑Guard™ silicone formulation to provide easier penetration and improved resealing compared to standard septa. This helps extend instrument uptime, reduce missed injections, and improve reproducibility in demanding analytical workflows.
Pre‑slit septa are commonly recommended for Waters® Alliance and Acquity systems. While the X‑slit design enhances penetration and targeting, it provides slightly reduced resealing compared to single‑slit septa. The bonded PTFE/silicone septa deliver strong chemical resistance, while the yellow cap supports clear identification and efficient workflow organization.
