Catalog Number - 9502S-30C-G-M

The 9502S‑30C‑G‑M MICROSOLV™ Screw Caps are selected for chromatography workflows requiring reliable pre‑slit septa performance and consistent autosampler injections. The bonded silicone rubber/PTFE septa design helps minimize septa plunge, dislodgement, and septa movement during repeated injections.

Manufactured with green knurled polypropylene caps and precision pre‑slit silicone/PTFE septa, these caps are designed for use with standard 9‑425 thread, 12 × 32 mm autosampler vials. The pre‑slit configuration supports smoother needle penetration and dependable resealing performance for routine HPLC and GC workflows.
