Description
DURAN® threaded tube GL 25 with NS 24/29 cone is a laboratory glass connector that combines a DIN screw thread with a standard ground joint (NS cone). Made from borosilicate glass 3.3, it allows apparatus components to be joined securely at both ends, supporting modular assembly of glass systems. The ground joint delivers a tight seal while the DIN thread enables reliable screw connections in laboratory setups. This configuration is intended for installation in glass apparatus. Supplied in packs of 10 pieces, the tube is offered by manufacturer Duran/DWK Life Sciences under the DURAN® brand. Certain threaded-pipe length and thread combinations are special sizes and not according to DIN ISO; the GL 25 / NS 24/29 design provides a practical linking element for research and analytical glassware. Chemical resistance and thermal behaviour characteristic of borosilicate glass 3.3 support routine use in laboratory glass constructions where both threaded and ground-joint interfaces are required.

Questions about DURAN® Tube with Screw Thread, with DIN thread, and standard ground cone
What is this article?
DURAN® Tube with Screw Thread, with DIN thread, and standard ground cone is the article on this page. Luminix Health distributes DWK Life Sciences 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.
