Description
Angle high-vacuum valve with PTFE spindle and a bore of 0–10 mm is a precision glassware component for vacuum line control in laboratory setups. This adjustable corner-style valve features a polytetrafluoroethylene (PTFE) spindle that enables fine regulation of the flow path from fully closed to a maximum opening of 10 mm. The valve body is made of borosilicate glass 3.3 and incorporates a tube connection with an outer diameter of 22 mm for integration into standard laboratory vacuum apparatus. Supplied as a single piece from manufacturer Rettberg, the design supports high-vacuum applications where chemical resistance and reliable sealing are required. The PTFE spindle provides low friction and chemical inertness during repeated adjustment. With a net weight of 0,059 kg, the compact valve suits bench-scale and glass vacuum manifolds. Laboratories working with high-vacuum systems can use this angle configuration to route and isolate vacuum lines efficiently while maintaining the integrity of the glass apparatus.

Questions about High vacuum valve, angled 90°, PTFE-spindle, passage 0 - 10 mm,
What is this article?
High vacuum valve, angled 90°, PTFE-spindle, passage 0 - 10 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Robinets & vannes, inside Tubes, tuyaux et raccords, in Matériel de laboratoire.
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.
