Catalog Number - 9502S-40C-G

The 9502S‑40C‑G MICROSOLV™ Screw Caps are selected for chromatography workflows requiring softer septa materials that help reduce stress on autosampler needles and injection systems. The bonded orange‑red rubber/PTFE septa configuration supports reliable sealing while minimizing septa movement during autosampler operation.

Manufactured with green knurled polypropylene caps and bonded orange‑red rubber/PTFE septa, these caps are designed for use with standard 9‑425 thread, 12 × 32 mm autosampler vials. The softer orange‑red rubber material is more economical than white silicone rubber while remaining softer than natural red rubber for improved autosampler compatibility.
