Description
Cone NS 19/26 extension is a precision ground-joint component intended for laboratory glassware assemblies needing an extended male cone. Manufactured to DIN 12249 PRECISO specifications, this NS cone with extension provides a nominal joint size of NS 19/26, an outer diameter of 17 mm, an overall length of 150 mm and a wall thickness of 1,8 mm. The added length improves reach and alignment when connecting distillation columns, extractors or reaction vessels. Available in packs of 10 pieces from manufacturer Witeg, the cones deliver reliable, interchangeable joints for everyday laboratory glass systems. With a net weight of 0,022 kg per piece, the component stays light yet dimensionally stable. It is well suited to research, analytical and educational laboratories that rely on standardised European ground joints, fitting directly into existing NS 19/26 apparatus and supporting consistent geometry throughout multi-part glassware trains.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about ST-Cones, ST 19/26, skirted
What is this article?
ST-Cones, ST 19/26, skirted 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.
