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

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

The 9502C‑E‑30K‑M Soft‑Guard™ Snap Caps combine pre‑slit septa design with advanced Soft‑Guard™ silicone formulation to optimize both penetration and resealing. The pre‑slit reduces resistance during autosampler needle entry, while the Soft‑Guard™ material enhances resealing compared to standard septa—helping extend instrument uptime, reduce missed injections, and improve overall data reliability.

Pre‑slit septa are commonly recommended for autosampler systems such as Waters® Alliance and Acquity, where consistent needle entry and reduced penetration force are critical for optimal performance.

The bonded PTFE/silicone septa provide strong chemical resistance and protect sample integrity across HPLC and LC‑MS workflows. The black polyethylene cap offers light‑blocking properties, making it particularly useful for light‑sensitive samples while also supporting color‑coded workflow organization in high‑throughput laboratories.
