Additional Info:
Soft‑Guard™ septa utilize a specialized silicone formulation that reduces coring while maintaining elasticity for repeat injections. The bonded PTFE/silicone septa provide chemical resistance and sample protection, making these caps suitable for HPLC, GC, LC‑MS, and GC‑MS applications.
The 9502S‑E‑10C‑N Soft‑Guard™ Screw Caps are engineered to improve autosampler performance through easier needle penetration and superior resealing compared to conventional septa. This design helps minimize missed injections, extend septa life, and support more consistent analytical results.
The natural translucent polypropylene cap with knurled exterior ensures secure handling and proper torque during cap application. These caps are fully compatible with 9‑425 screw thread, 12 × 32 mm autosampler vials.
