Catalog Number - 9502S-E-3XK

The 9502S‑E‑3XK Soft‑Guard™ Screw Caps are selected for chromatography workflows requiring easier autosampler needle entry and improved needle targeting. The X‑shape pre‑slit septa design provides a larger target area for autosampler needles and reduces penetration resistance during injection.

Manufactured with black knurled polypropylene caps and fitted Soft‑Guard™ white silicone rubber/red PTFE 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.
