Catalog Number - 9502S-40C-B-M

The 9502S-40C-B-M Screw Caps are designed for use with standard 9-425 thread, 12 x 32 mm autosampler vials. Featuring bonded Orange-Red Silicone Rubber / PTFE septa installed in blue knurled polypropylene caps, they provide reliable sealing and sample protection for routine laboratory applications.

The softer orange-red silicone formulation offers a more economical alternative to traditional white silicone rubber while helping reduce stress on autosampler needles during repeated injections. This can help minimize wear on injection systems and support long-term instrument performance.

The PTFE-facing layer provides chemical inertness, while the bonded septa construction helps prevent septa movement or dislodgement during autosampler operation. Packaged 1000 per case, these caps are ideal for high-throughput laboratories seeking dependable performance and value.
