Catalog Number - 9502S-09-PS

AQ™ PFAS-Compatible Screw Caps are designed for laboratories performing PFAS analysis, environmental testing, sample storage, and routine chromatographic workflows where PTFE-containing components must be avoided. These black knurled caps feature a silicone rubber liner with a polypropylene facing, providing an excellent combination of sealing performance, chemical inertness, and sample protection for sensitive analytical applications.

9502S-09-PS is a custom-order cap configured specifically for use in PFAS testing and sample storage applications. The polypropylene-facing liner does not contain PTFE, making it suitable for workflows where minimizing potential fluoropolymer-related contamination is critical. The silicone rubber backing provides reliable sealing performance to help maintain sample integrity before and after chromatographic analysis.

Designed for compatibility with 9 mm screw thread autosampler vials, these caps deliver reliable performance on MICROSOLV, AQ™, and RSA™ branded vial systems. The knurled cap design provides improved grip for easy installation and removal, making them ideal for high-throughput analytical laboratories, environmental testing facilities, and PFAS monitoring programs.
