Description
Angle vacuum valve with an adjustable passage of 0 - 4 mm offers right-angle flow regulation for laboratory vacuum systems. Equipped with a PTFE spindle that can be readjusted, the valve enables accurate control of the opening and secure closure. Construction from borosilicate glass 3.3 provides excellent chemical resistance, low thermal expansion and reliable mechanical strength under vacuum. The polytetrafluoroethylene spindle ensures chemical inertness, supporting contamination-free operation with a wide variety of laboratory media. Supplied as one piece with a net weight of 0,033 kg, the component fits readily into glass vacuum lines, manifolds and compact apparatus layouts. Produced by manufacturer Rettberg, it is intended for scientific and research settings that demand durable glassware valves in an angle format. Typical applications encompass vacuum distillation, Schlenk-line connections, freeze-drying setups and general vacuum transfer where a 90-degree orientation improves routing of tubing. The adjustable spindle design allows users to optimise sealing and flow characteristics throughout the service life of the valve.

Questions about Vacuum-valve, right angled, 0 - 4 mm, PTFE-spindle, adjustable
What is this article?
Vacuum-valve, right angled, 0 - 4 mm, PTFE-spindle, adjustable is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, 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.
