Catalog Number - 9502S-30C-KPS-M

Provide PFAS‑compatible sealing with advanced septa materials designed to eliminate PTFE while maintaining strong analytical performance.

9502S-30C-KPS-M caps feature a unique bonded septa design using translucent silicone for optimal sealing and clear polypropylene for inertness, without the use of PTFE. This makes them especially suitable for Polyfluoroalkyl Substances (PFAS) testing, where avoiding fluoropolymer materials is critical to prevent contamination and achieve accurate results.

The pre‑slit septa allows smooth and consistent needle penetration while maintaining reliable resealing during repeated injections. The bonded construction prevents septa movement or “septa plunge,” improving autosampler consistency and performance. The knurled polypropylene cap ensures secure handling and efficient processing in high‑volume laboratory environments.

Use with AQ™ Brand or RSA™ Brand 9 mm screw thread autosampler vials for optimal sealing performance and system compatibility.
