Description
Socket joint DURAN (Form E) NS 14/23 is a precision ground glass component intended for reliable connections in laboratory glassware. Fabricated from borosilicate glass 3.3, it features the standard taper size NS 14,5/23, a tube diameter of 17 mm and a wall thickness of 1,8 mm. With an overall length of 135 mm and a net weight of 0,022 kg, the joint remains compact yet robust for vacuum distillation, reflux apparatus and multi-component reaction systems. The Form E design guarantees consistent fit with corresponding cone joints, while the material’s excellent chemical inertness and thermal-shock resistance permit use across a broad temperature range. This socket joint from manufacturer Rettberg supports modular construction of custom DURAN-compatible assemblies for synthesis, purification or analytical tasks. Supplied as one piece, it enables straightforward replacement or extension of existing setups while preserving dimensional precision and seal integrity.

Questions about Joint socket/DURAN (shape E) size 14/23
What is this article?
Joint socket/DURAN (shape E) size 14/23 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
