Description
Angle high-vacuum valve with PTFE spindle and bore 0 - 6 mm provides adjustable control for laboratory high-vacuum systems. Constructed from borosilicate glass 3.3 and fitted with a polytetrafluoroethylene (PTFE) spindle, the valve offers excellent chemical inertness and mechanical reliability. The tube connection has an outer diameter of 10 mm, ensuring compatibility with standard laboratory glass tubing, and the unit weighs 0,064 kg for convenient handling. Its adjustable mechanism allows precise setting of the bore from closed to a maximum of 6 mm, supporting both isolation and regulated flow of gases or vapours. This angle configuration is well suited to vacuum manifolds, inert-atmosphere techniques, distillation apparatus and other reduced-pressure applications. Supplied by manufacturer Rettberg, the valve serves as a durable stopcock or shut-off element in research and analytical laboratories. The combination of borosilicate glass and PTFE ensures long service life under repeated thermal cycling and exposure to aggressive media while maintaining vacuum integrity in compact glass assemblies.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about High vacuum valve, angled 90°, PTFE-spindle, passage 0 - 6 mm,
What is this article?
High vacuum valve, angled 90°, PTFE-spindle, passage 0 - 6 mm, 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.
