Description
Transition piece with cone NS 45 and socket NS 29,2 links laboratory glassware that uses these two standard ground-joint sizes. The cone NS 45 fits a corresponding larger socket, while the socket NS 29,2 receives apparatus finished to NS 29,2, providing a defined step-down within a multi-joint assembly. Transition pieces of this type are standard accessories for building or adapting distillation trains, reaction apparatus and other ground-joint systems when components of different nominal sizes must be combined. Supplied as one piece from manufacturer Starke, the adapter supports flexible laboratory glassware layouts and inventory standardisation around common NS dimensions. Explicit cone and socket markings facilitate correct orientation and pairing during setup. It is intended for general laboratory material use wherever a robust NS 45 to NS 29,2 transition is needed in research or routine work.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Transition pieces Core NS 45 - Sleeve NS 29.2
What is this article?
Transition pieces Core NS 45 - Sleeve NS 29.2 is the article on this page. Luminix Health distributes Starke 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.
