DURAN® cones with collar, with drain, NS 19/26 are precision ground joint components for modular laboratory glassware systems. These male cones incorporate a collar together with an integrated drain outlet and follow the NS 19/26 standard taper, ensuring interchangeability with matching sockets in distillation, reaction and separation assemblies. The collar design adds mechanical support during connection and disconnection of apparatus, while the drain facilitates controlled emptying or sampling of liquids within the joint area. Supplied as a single piece, the component belongs to the established DURAN® range from manufacturer Duran/DWK Life Sciences and is intended for everyday use in chemical, analytical and educational laboratories that rely on standardised ground-joint connections. It supports flexible apparatus configurations for organic synthesis, solvent handling and general wet-chemistry workflows where reliable, reusable joints are required. The NS 19/26 size is widely employed in medium-scale glass setups, allowing straightforward integration without additional adapters in many common laboratory arrangements.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about DURAN® Cones with ridge, with tip, NS 19/26
What is this article?
DURAN® Cones with ridge, with tip, NS 19/26 is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labmateriaal.
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.
