These unique Screw Caps can be used for almost any sample but are designed for Polyfluoroalkyl Substances (PFAS) testing in our Autosampler Vials. The silicone rubber (for optimal sealing), and Polypropylene fitted Septa (for inertness) are excellent for chromatography. These caps do not contain PTFE like most other autosampler vial caps.
