Description
Ventilation valve GreenLine for PFAS analysis is a dedicated laboratory component that protects solvents from airborne contamination in HPLC systems. Equipped with a UNF 1/4'' 28G thread, the valve incorporates a PTFE filter for clean solvent delivery and an integrated membrane that blocks solvent vapours. A built-in time indicator marks the recommended replacement interval of 6 months, supporting both analytical and preparative chromatography. The GreenLine valve from manufacturer SCAT is designed for use with SCAT Safety Caps and is particularly suited to PFAS-related workflows where solvent integrity is critical. Constructed from polypropylene (PP), it prevents uptake of ambient impurities while maintaining reliable vapour containment. Supplied as a single piece, the valve offers a straightforward solution for laboratories seeking to safeguard solvent pathways and reduce contamination risk during sensitive liquid-chromatography applications. Its focused design contributes to consistent system performance in routine and specialised analytical environments.

Questions about Air Valve, GreenLine, PFAS Analytic, PU = 1 pc
What is this article?
Air Valve, GreenLine, PFAS Analytic, PU = 1 pc is the article on this page. Luminix Health distributes SCAT for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
