Description
Ventilation valve GreenLine for PFAS analysis is a specialised air-inlet component that protects solvents from airborne contamination in HPLC and related chromatographic systems. Equipped with a UNF 1/4'' 28G thread, the valve integrates a PTFE filter that ensures clean solvent supply together with a membrane that reliably blocks solvent vapours. It is intended for both analytical and preparative work and carries a built-in time indicator showing the recommended exchange point after six months of service. Supplied as a pack of ten pieces and manufactured from polypropylene (PP), these valves from manufacturer SCAT are designed for use with SCAT Safety Caps. By preventing the ingress of ambient impurities they help maintain solvent integrity, which is especially critical in sensitive PFAS workflows. The GreenLine design combines straightforward installation with dependable long-term protection against contamination, supporting consistent analytical results in routine laboratory operation.

Questions about Air Valve, GreenLine, PFAS Analytic, PU = 10 pcs
What is this article?
Air Valve, GreenLine, PFAS Analytic, PU = 10 pcs 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.
