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

Soft‑Guard™ septa are designed to reduce needle resistance while maintaining strong resealing performance, helping improve injection consistency and reduce autosampler downtime.

The 9502S‑E‑10C‑R Soft‑Guard™ Screw Caps use a specialized silicone formulation that minimizes coring and maintains elasticity over multiple injections. The bonded PTFE/silicone septa provide chemical resistance and protect sample integrity across HPLC, GC, LC‑MS, and GC‑MS workflows.

The red polypropylene cap allows easy visual identification and features a knurled exterior for secure handling and consistent sealing on standard 9‑425 thread, 12 × 32 mm autosampler vials.
