Caps, Screw Top, with Orange Red Rubber / PTFE Septa, bonded in "knurled", polypropylene, Green Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 1000/CS.
Additional Info:
The 9502S‑40C‑G‑M 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.
