Description
3-Way high-vacuum valve stopcock 6 mm is a laboratory stopcock intended for high-vacuum applications that require a larger bore. The red Witaflo model features a 6 mm bore, an overall length of 220 mm and a 10 mm stem for connection to vacuum glassware and manifold systems. Delivered as a single piece with a net weight of 0,155 kg, this three-way valve stopcock enables directional switching and isolation in distillation, gas-handling and vacuum-line setups. From manufacturer Witeg, the stopcock belongs to the range of laboratory valves and stopcocks used for controlled routing under high-vacuum conditions. The combination of bore size, overall length and stem diameter supports integration into medium-scale apparatus where a 6 mm passage is preferred. Clear dimensional data help laboratories select the correct stopcock for existing glass assemblies. The red colour coding aids visual identification on the bench. The product is suited to chemistry and analytical laboratories that maintain high-vacuum systems and need a defined three-way valve stopcock with specified geometry.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about three-way-high-vacuum-stopcock, 6 mm
What is this article?
three-way-high-vacuum-stopcock, 6 mm is the article on this page. Luminix Health distributes Witeg 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.
