Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance.
The 9502C‑E‑10C‑M Soft‑Guard™ Snap Caps are one of the most popular snap cap configurations, combining ease of use with advanced septa performance. The Soft‑Guard™ silicone formulation is engineered to reduce needle penetration force while maintaining excellent resealing, helping extend instrument uptime and minimize missed injections in demanding analytical environments.
The bonded PTFE/silicone septa provide strong chemical resistance and protect sample integrity across HPLC and LC‑MS workflows. The natural (transparent) polyethylene cap allows visual inspection and alignment while maintaining durability and consistent sealing performance. This makes it especially useful for workflows where sample visibility or cap identification without color interference is beneficial.
