Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining reliable autosampler performance.
The 9502C‑E‑10K‑M Soft‑Guard™ Snap Caps are part of MICROSOLV’s most popular snap cap family, offering consistent, high‑performance sealing in demanding laboratory environments. The Soft‑Guard™ silicone formulation is engineered to reduce needle penetration force while maintaining excellent resealing characteristics, helping extend instrument uptime and reduce missed injections.
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 suitable for light‑sensitive samples while also supporting clear visual differentiation in color‑coded workflows.
