CUSTOM ITEM: Caps, Snap Top, with Soft-Guard, White Silicone Rubber / Red PTFE Pre-Slit (X Shape) Septa, fitted in smooth, polyethylene, Red Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. Soft-Guard Brand. 1000/CS. 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, making alignment easier and reducing penetration resistance during injection.
The 9502C‑E‑30RX‑M Soft‑Guard™ Snap Caps combine this X‑slit design with advanced Soft‑Guard™ silicone formulation to deliver easier penetration while maintaining improved resealing compared to standard septa. This helps extend instrument uptime, reduce missed injections, and improve consistency in high‑throughput analytical workflows.
Pre‑slit septa are commonly recommended for Waters® Alliance and Acquity systems. While the X‑slit enhances ease of penetration and targeting, it provides slightly reduced resealing compared to single‑slit septa. The bonded PTFE/silicone septa ensure strong chemical resistance, while the red cap supports clear identification and efficient workflow organization.
