Description
DURAN® threaded tube with GL 14 DIN thread and NS cone 29/32 is a specialised glass connector for laboratory apparatus. Fabricated from borosilicate glass 3.3, it combines a precision screw thread with a standard ground joint core, allowing components to be joined securely from both ends. The ground joint ensures a tight seal while the DIN thread enables reliable screw-based connections in modular glass systems. This design supports flexible assembly of multi-component setups used throughout chemical synthesis, distillation and analytical workflows. Available as a single piece with a net weight of 0,022 kg, the tube offers the chemical resistance and thermal performance expected from borosilicate 3.3 glassware. Produced by Duran/DWK Life Sciences under the DURAN® brand, it is intended for installation in glass apparatus. Certain length and joint combinations, including the GL 14 / NS 29/32 variant, are special sizes not conforming to DIN ISO. Laboratories benefit from its inert surface and dimensional accuracy when building custom glass assemblies requiring durable, leak-tight interfaces between threaded and ground-joint components.

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.
