Description
Ventilation valve V2.0 is a specialised air-inlet valve for SCAT Safety Caps that prevents uptake of ambient contaminants and blocks solvent vapours on HPLC systems. The valve carries a UNF 1/4'' 28G thread and incorporates a PTFE filter to maintain clean solvent supply for both analytical and preparative applications. An integrated valve membrane stops solvent vapour escape while the valve itself protects the solvent reservoir from impurities drawn from surrounding air. Each unit is fitted with a time indicator that signals the recommended replacement after a service life of 6 months. Supplied in a pack of 100 pieces from manufacturer SCAT, these V2.0 ventilation valves help preserve solvent integrity throughout HPLC operation. Regular exchange according to the built-in 6-month indicator ensures continued protection against contamination. The design is intended for direct use with SCAT Safety Caps on analytical and preparative liquid-chromatography installations where solvent purity is essential.

Questions about Air Valve, V2.0, PU = 100 pcs
What is this article?
Air Valve, V2.0, PU = 100 pcs is the article on this page. Luminix Health distributes SCAT for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
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.
