Description
Long ground joint cone extension NS 24/40 is a precision laboratory glass component for standardised conical ground-joint assemblies. This NS long cone with extension is offered in the PRECISCO series for joint size NS 24/40, with an outer diameter of 22 mm, a length of 150 mm and a wall thickness of 1,8 mm. The elongated cone design allows practical spacing and alignment when connecting reaction vessels, condensers and adapters while maintaining a secure ground-glass interface. Units are supplied in packs of 10 pc(s), each with a net weight of 0,035 kg. Produced by manufacturer Witeg, the item belongs to the standard ground-joint range common in organic synthesis, distillation and general laboratory glassware systems. NS 24/40 is a frequently used joint format, so the extension integrates readily with matching sockets and intermediate pieces. Controlled diameter, length and wall thickness support consistent, interchangeable fits across multi-piece apparatus where reliable sealing and mechanical stability are important.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about ST-Cones, full length, skirted, ST 24/40
What is this article?
ST-Cones, full length, skirted, ST 24/40 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.
