Description
Angle valve "Witaflo" 3 mm is a high-vacuum corner valve designed for laboratory glass apparatus. The valve stem is manufactured from pure PTFE, providing chemical resistance and smooth operation under vacuum conditions. Bore diameter is 3 mm, leg outer diameter 8 mm and overall length 75 mm, finished with a GL 14 thread connection. Fabricated from DURAN tubing, the body offers the thermal and chemical durability expected of borosilicate laboratory glassware. This single-piece unit from manufacturer Witeg is intended for high-vacuum lines, Schlenk-type setups and gas-handling manifolds where a compact angle configuration and reliable PTFE sealing are required. Net weight is 0,04 kg. The Witaflo design supports repeated open–close cycles while maintaining vacuum integrity in research and preparative chemistry environments.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about angled high vacuum valve Witaflo 3 mm
What is this article?
angled high vacuum valve Witaflo 3 mm 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.
