Description
Conical ground joint socket NS 19/26 is a robust laboratory glassware joint for interchangeable conical connections on medium-capacity apparatus. Manufactured to DIN 12249, this female socket (Hülse) follows the NS 19/26 standard taper used extensively for reaction flasks, condensers, receivers and multi-neck assemblies. The larger joint face relative to smaller NS sizes provides a stable mechanical seal for greasable conical mates under atmospheric or vacuum-assisted conditions common in preparative work. Supplied as a single piece from manufacturer Schlee, it supports modular glass trains where components must be swapped, cleaned and recombined without loss of fit. NS 19/26 is a practical choice for research and teaching environments that standardise on mid-range European joint sizes for distillation, reflux, extraction and general synthesis. DIN-conform dimensions promote cross-compatibility with other conforming cones and adapters, simplifying stock management. Specify this socket when building or maintaining apparatus that relies on reliable NS 19/26 conical interfaces and consistent laboratory joint performance.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Conical joints according DIN 12449, socket NS 19/26
What is this article?
Conical joints according DIN 12449, socket NS 19/26 is the article on this page. Luminix Health distributes Schlee for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Matériel de laboratoire.
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.
