Caps, Screw Top, with Silicone Rubber / Polypropylene Septa, in "knurled", Polypropylene Blue Caps. AQ Brand. 1000/CS.
Additional Info:
The 9502S‑10C‑PS‑M screw caps are engineered without PTFE, making them an ideal choice for Polyfluoroalkyl Substances (PFAS) testing and other analytical workflows where PTFE materials must be avoided.
These caps combine silicone rubber for reliable sealing with polypropylene septa for chemically inert sample contact, delivering excellent performance in chromatographic applications while eliminating PTFE‑related contamination risks. This design allows the caps to be used with a wide range of samples, with specific emphasis on PFAS compliance testing.
For optimal sealing and autosampler performance, these caps are recommended for use with AQ™ brand or RSA™ brand 9 mm screw‑thread autosampler vials.
This 1000‑count case format is ideal for high‑throughput laboratories conducting routine or regulated PFAS analysis.
