TAMPA P/VIAL 9mm POLIETILENO, TOPO SOLIDO, SEM PTFE RESTEK

2.0 mL, 9 mm Solid-Top Polyethylene Caps Compatible with all 9 mm screw-thread vials. Molded, 10 mil, solid, pierceable cap. PTFE-free—ideal for PFAS analysis (e.g., EPA 537) and other PFAS-sensitive methods. Note: Polyethylene caps prevent sample contamination from PTFE-coated septa. However, since polyethylene caps do not reseal, evaporation occurs after injection. Multiple injections from the same vial are therefore not possible.
