Description
Ground joint socket NS 14/23 is a standardised female joint for laboratory glassware connections according to DIN 12249. Featuring the widely used NS 14/23 taper, it has an outer diameter of 17 mm, a length of 120 mm and a wall thickness of 1,8 mm, making it a practical choice for medium-scale apparatus. The component is supplied as a single piece with a net weight of 0,023 kg and is intended for pairing with matching cones in synthesis, distillation, reflux and general laboratory workflows. Its DIN-compliant dimensions allow straightforward integration into multi-neck flasks, adapters, condensers and receiving vessels that share the NS 14/23 format. From manufacturer Witeg, this socket supports interchangeable Normschliff systems where repeatable fit and clear dimensional specification are required. Laboratories in research, quality control and education benefit from the consistent geometry for building and modifying glassware trains without specialised tooling. Outer diameter, length and wall thickness are fully defined to aid selection, replacement and inventory control across modular ground-joint assemblies.

Questions about Socket ST 14/23
What is this article?
Socket ST 14/23 is the article on this page. Luminix Health distributes Witeg 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.
