Description
3-Way high-vacuum valve stopcock 3 mm is a laboratory stopcock for high-vacuum work in chemical, analytical and research glass systems. The Witaflo design provides a 3 mm bore, an overall length of 215 mm and an 8 mm stem for connection to compatible vacuum lines and apparatus. Supplied as a single piece with a net weight of 0,06 kg, this three-way valve stopcock supports directional control and isolation in vacuum manifolds, distillation setups and related laboratory assemblies. From manufacturer Witeg, the component fits standard categories of laboratory valves, stopcocks and shut-off devices used where controlled routing of vacuum pathways is required. The defined bore diameter and overall dimensions allow integration into smaller-scale high-vacuum glassware configurations. Laboratories that assemble or maintain vacuum lines benefit from the clear geometric specification of bore, length and stem size when matching the stopcock to existing apparatus. The unit is intended for routine high-vacuum laboratory use and is delivered ready for installation in three-way valve applications.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about three-way-high-vacuum-stopcock, 3 mm
What is this article?
three-way-high-vacuum-stopcock, 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 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.
