Catalog Number - 9502C-E-30RX

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 reduced resistance during penetration.

The 9502C‑E‑30RX 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 analytical workflows.

Pre‑slit septa are commonly recommended for Waters® Alliance and Acquity systems. While the X‑slit design enhances targeting and ease of penetration, it provides slightly reduced resealing compared to single‑slit septa. The bonded PTFE/silicone septa ensure strong chemical resistance, while the red cap enables clear identification and efficient workflow organization.
