Description
Extension made of DURAN® with socket 14/23 on core NS 29/32 is a ground-joint adapter-style glass component for laboratory apparatus. It bridges a smaller NS 14/23 socket to a larger NS 29/32 core, enabling connection between glassware sections of different joint sizes in distillation and extraction setups. Made of DURAN® and supplied as 1 pc from manufacturer Lenz, the piece weighs 0,042 kg. This socket-to-core configuration supports modular build-up of glass trains where a size transition is required without additional intermediate fittings. It forms part of the range of glass components with ground glass joints used alongside vessels and laboratory consumables in research, teaching and routine analytical environments. Standard NS designations help maintain interchangeability with existing jointed glassware. Offered as a single unit, the extension is practical for configuring or extending apparatus lines, adapting reach and aligning mixed joint sizes in organic work-up, solvent handling and related laboratory glass systems.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Extension made of DURAN®, Socket 14/23 on core NS 29/32, 1 unit(s)
What is this article?
Extension made of DURAN®, Socket 14/23 on core NS 29/32, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
