Catalog Number - 9502S-20C-G-M

The 9502S‑20C‑G‑M MICROSOLV™ Screw Caps are selected for chromatography workflows requiring enhanced needle cleaning action and improved resealing characteristics after injection. The triple‑layer red PTFE/white silicone/red PTFE septa configuration was developed for compatibility with certain older autosampler systems and applications where additional needle wiping performance is beneficial.

Manufactured with green knurled polypropylene caps and fitted multi‑layer septa, these caps are designed for use with standard 9‑425 thread, 12 × 32 mm autosampler vials. This septa configuration is commonly used with older instrument platforms comparable to Agilent 1050 systems.
