Catalog Number - 9502S-E-10C-G

The 9502S‑E‑10C‑G Soft‑Guard™ Screw Caps are selected for chromatography workflows requiring improved autosampler performance and enhanced septa resealing characteristics. The bonded Soft‑Guard™ white silicone rubber/red PTFE septa design helps reduce septa movement while supporting easier needle penetration and improved resealing compared to conventional septa configurations.

Manufactured with green knurled polypropylene caps and bonded Soft‑Guard™ septa, these caps are designed for use with standard 9‑425 thread, 12 × 32 mm autosampler vials commonly used in HPLC, GC, LC‑MS, and GC‑MS laboratories.
