Description
Angle high-vacuum stopcock valve "Witaflo" 3 mm is a laboratory stopcock intended for high-vacuum and controlled gas-flow applications. Built from DURAN tubing, the Witaflo angled valve incorporates over-rotation protection and provides a 3 mm bore for higher conductance than smaller-bore counterparts. The stem diameter is 8 mm and the overall length is 210 mm, allowing straightforward integration into vacuum manifolds, glass apparatus and bench-top vacuum lines. The angled geometry helps keep tubing and connections compact while maintaining reliable isolation of flow paths. Supplied as a single piece from manufacturer Witeg, this stopcock valve supports research, analytical and teaching environments that require robust DURAN-based high-vacuum components with a defined 3 mm bore for routine vacuum work and apparatus assembly.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Angled high vacuum stopcock ''Witaflo''
What is this article?
Angled high vacuum stopcock ''Witaflo'' is the article on this page. Luminix Health distributes Witeg 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.
