Safety Caps for PFAS Analytic feature a polypropylene core, which is free from PFAS to ensure the accuracy of PFAS testing without interference from the cap material. All associated accessories such as fittings, blind plugs, and ventilation valves are also PFAS-free.

• SCAT Safety Caps for PFAS Analytic are hermetically sealing closures for the safe supply of HPLC with solvents
• Caps are designed for use in tests that aim to detect the presence of fluorine in a substance
• Caps block harmful vapours and protect HPLC systems from contamination
• SCAT Air Valves block harmful vapours and ensure safe pressure equalisation in HPLC storage tanks
• Air Valves ensure solvent mixtures remain stable, thanks to closed system without evaporation
• SCAT Starter Kits are a plug and play solution for up to four storage bottles
• Starter Kits are ideal as initial equipment for an HPLC system

When a Safety Cap is said to be suitable for PFAS (Poly- and Perflouroalkyl Substances) analysis, it means that the cap is designed for use in tests that aim to detect the presence of fluorine in a substance. In this context, it would make sense for the cap not to contain fluorine, as the presence of PFAS (in this case PTFE) in the cap could potentially interfere with the accuracy of the analysis.

Therefore, SCAT offers Safety Caps with a polypropylene (PP) core, which is free from PFAS to ensure the accuracy of PFAS testing without interference from the cap material. The same approach is used for the fittings; normally they are made out of PFA (which contain fluori), for this special cap they are made out of PP, which means without PFAS. This is particularly important for laboratories and industries involved in PFAS analysis, where precision and the absence of contamination are crucial.
