Description
Transition piece with cone NS 24 and socket NS 29,2 connects ground-joint glassware of two different standard joint sizes in the laboratory. The cone side mates with an NS 24 socket, while the socket side accepts an NS 29,2 cone, allowing apparatus sections that would otherwise be incompatible to be joined in a single rigid glass link. This adapter format is a common laboratory material item for building or modifying distillation, reaction and vacuum setups where joint sizes must be bridged without improvised tubing. Supplied as a single piece from manufacturer Starke, the transition piece is intended for routine assembly of borosilicate ground-joint systems in research and quality-control laboratories. Using a dedicated cone-to-socket reducer keeps the glass train aligned, reduces leak paths compared with multi-piece workarounds and preserves the sealing geometry of each standard joint. The NS 24 / NS 29,2 pairing is specified clearly on the component so that inventory matching and apparatus planning remain straightforward when expanding or reconfiguring existing glassware manifolds.

Questions about Transition pieces Core NS 24 - Sleeve NS 29.2
What is this article?
Transition pieces Core NS 24 - 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.
