If Per- and Polyfluoroalkyl (PFAS) substances don’t break down, they can accumulate over time in the environment and in the human body. Finneran Porvair R.A.M™ screw thread vials have been designed for PFAS analyses. They are manufactured from chemically resistant polypropylene to handle “PFAS-free” sampling, testing, storage, and transporting tasks. The company claims the new closure has a useable temperature range up to 130°C, while the liner performs up to ten injections.
