Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance.
The 9502C‑E‑10C Soft‑Guard™ Snap Caps are among the most popular snap cap configurations, combining convenience 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 reduce missed injections.
The bonded PTFE/silicone septa deliver strong chemical resistance and protect sample integrity across HPLC and LC‑MS workflows. The natural (transparent) polyethylene cap allows clear visual inspection of the septa and contents alignment while maintaining the same durability and handling performance as colored caps.
