Description
High-vacuum straight-through valve, 0 – 15 mm, with PTFE spindle is a robust laboratory fitting designed for isolation and regulated flow in high-vacuum systems. The body is fabricated from borosilicate glass 3.3 and fitted with a fine-thread PTFE spindle that permits continuous control of the passage from 0 to 15 mm. Tube ends have an outer diameter of 20 mm for connection to larger-diameter glass tubing commonly used in vacuum manifolds. At a net weight of 0,181 kg the valve remains practical for bench-scale and pilot assemblies. Borosilicate glass together with the PTFE spindle ensures chemical resistance and grease-free operation with typical laboratory solvents and reagents. This high-vacuum straight-through valve from manufacturer Rettberg is appropriate for distillation apparatus, Schlenk lines and analytical vacuum installations in research and industrial laboratories. The straight-through configuration limits dead volume and pressure loss, supporting efficient vacuum performance in chemistry and materials-science environments.

Questions about High vacuum valve, straight, 0 - 15 mm, with PTFE-spindle,
What is this article?
High vacuum valve, straight, 0 - 15 mm, with PTFE-spindle, is the article on this page. Luminix Health distributes Rettberg 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.
