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

Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance.

The 9502C‑E‑30B‑M Soft‑Guard™ Snap Caps combine a pre‑slit septa design with advanced Soft‑Guard™ silicone formulation to optimize both penetration and resealing. The pre‑slit reduces needle resistance during injection, while the Soft‑Guard™ material improves resealing compared to standard septa. This helps extend instrument uptime, reduce missed injections, and support more consistent analytical results.

Pre‑slit septa are commonly recommended for systems such as Waters® Alliance and Acquity instruments, where smooth needle entry and repeatability are critical. The bonded PTFE/silicone septa provide strong chemical resistance and sample protection across HPLC and LC‑MS workflows.

The smooth blue polyethylene cap allows for quick application and removal, making it well suited for high‑throughput laboratory environments.
