Description
Straight-through high-vacuum stopcock 10/225 mm is a precision glass valve intended for high-vacuum laboratory systems and manifold work. Finished in the Witaflo brand colour red and equipped with over-rotation protection, it provides a 10 mm bore, an overall length of 225 mm and a stem diameter of 13 mm. Manufactured from DURAN tubing, this stopcock from manufacturer Witeg delivers reliable sealing performance in vacuum lines, gas-handling apparatus and glassware assemblies. The straight-through configuration allows unobstructed flow when open and secure isolation when closed, supporting clean vacuum pathways. Over-rotation protection helps protect the plug and barrel during frequent operation and maintenance. DURAN glass construction offers the chemical resistance and dimensional stability needed for demanding laboratory vacuum service. Ideal for research, analytical chemistry and process development laboratories, the stopcock can be incorporated into new apparatus or fitted as a replacement component. Supplied as a single piece, it is ready for installation in standard high-vacuum glass setups where controlled flow and dependable shut-off are required.

Questions about High vacuum needle valve stopcock 10/225
What is this article?
High vacuum needle valve stopcock 10/225 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.
