Description
Glass flange, standard, DN 50 is a robust small flange fabricated from borosilicate glass 3.3 according to DIN 28403. It is engineered for laboratory vacuum technology and process glassware and can be joined directly to corresponding DIN metal flanges, allowing flexible hybrid assemblies. Borosilicate glass 3.3 delivers outstanding chemical inertness together with good thermal stability, so the flange withstands repeated temperature changes and vacuum conditions common in research and production environments. Offered as a single unit with a net weight of 0,183 kg, the component fits standard DN 50 connection points used in larger glass apparatus, reactors and transfer lines. Precise geometry guarantees reliable sealing faces and mechanical strength under normal laboratory stresses. Produced by Rettberg, this standard glass flange serves as a durable, corrosion-resistant linking element for modular systems that require the performance characteristics of borosilicate glass 3.3. It is well suited to construction and maintenance of vacuum manifolds, distillation setups and process vessels where dimensional conformity and material purity are essential.

Questions about Glass flange, standard, DN 50
What is this article?
Glass flange, standard, DN 50 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
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.
