Catalog Number - 9502C-E-30YX-M

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‑M 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 high‑throughput 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.
