Caps, Screw Top, with Silicone Rubber / Polypropylene Septa, in "knurled", Polypropylene Blue Caps. AQ Brand. 100/PK.
Additional Info:
The 9502S‑10C‑PS screw caps are uniquely designed without PTFE, making them ideal for Polyfluoroalkyl Substances (PFAS) testing and other applications where PTFE materials may interfere with analytical results.
These caps combine silicone rubber for optimal sealing with polypropylene septa for inert sample contact, delivering excellent performance in chromatographic workflows while eliminating PTFE exposure entirely. This construction allows the caps to be used with almost any sample, with specific suitability for PFAS analysis.
For best sealing and autosampler performance, these caps are recommended for use with AQ™ brand or RSA™ brand 9 mm screw‑thread autosampler vials.
This 100‑count package is well suited for laboratories performing routine or compliance PFAS testing.
