Catalog Number - 9502S-09-PS-M

Designed for large‑scale laboratory operations and PFAS‑sensitive workflows, these bulk custom screw caps provide a reliable, PTFE‑free sealing solution for sample storage and transport.

9502S‑09‑PS‑M caps feature a solid, non‑pierceable design with a silicone rubber / polypropylene liner combination that provides excellent sealing performance while maintaining an inert sample contact surface. The absence of PTFE makes these caps ideal for PFAS testing and storage applications, where fluoropolymer contamination must be avoided.

Engineered for compatibility with standard 9 mm screw thread autosampler vials, these caps are recommended for use with MICROSOLV, AQ™, or RSA™ branded vials to ensure optimal sealing. The knurled design offers improved grip for manual handling, while the bulk case configuration (1000 caps) supports high‑throughput laboratories requiring consistent consumable supply for regulated and validated methods.
