Catalog Number - 9502S-80C-B

These 9-425 Screw Caps are designed for use with standard 12 x 32 mm autosampler vials and feature Natural Rubber / TFE septa fitted into blue knurled polypropylene caps. This are intended for laboratories requiring septa materials that differ from more commonly used silicone-based alternatives.

9502S-80C-B utilizes Natural Rubber septa that do not contain siloxanes commonly found in silicone rubber formulations. This can make them useful for analytical methods where siloxane-related interference is a concern. The TFE-facing layer provides chemical resistance and sample protection comparable to PTFE-facing materials used in many laboratory closures.

The knurled polypropylene cap design provides secure handling and consistent tightening, while the septa construction supports reliable vial sealing for routine autosampler applications. These caps are compatible with industry-standard 9-425 threaded vial systems used in HPLC, UHPLC, GC, and LC-MS laboratories.
