Catalog Number - 9582S-20C-K-M

The 9582S‑20C‑K‑M BASIK™ Screw Caps are selected for chromatography workflows requiring enhanced needle cleaning action and improved resealing performance during repeated injections. The PTFE/silicone/PTFE septa configuration was developed for compatibility with older autosampler systems where additional mechanical needle wiping is beneficial.

Manufactured with black knurled polypropylene caps and fitted multi‑layer septa, these caps are designed for use with standard 8‑425 thread, 12 × 32 mm autosampler vials. This septa configuration is commonly used with older instrument platforms comparable to Agilent 1050 systems.
