Vials & Caps for PFAS Testing

Vials and caps for PFAS testing are specialised laboratory consumables designed to support accurate, trace-level analysis of per- and polyfluoroalkyl substances (PFAS) while minimising the risk of contamination. As persistent environmental pollutants commonly analysed using chromatography techniques, PFAS can be introduced from standard laboratory materials – particularly PTFE-containing components – making careful material selection essential.

PFAS-optimised vials are typically manufactured from inert polypropylene, while PFAS-compatible caps utilise septa free from PTFE to help prevent leaching and unwanted background interference. Compatible with major autosamplers and suitable for established regulatory methods, they help laboratories maintain sample integrity, reduce the risk of false positives, and achieve consistent, reproducible performance in demanding PFAS workflows.
