Description
Transition piece cone NS 18,8 – socket NS 29,2 is a laboratory ground-joint adapter for connecting apparatus parts that use different standard joint sizes. One end is executed as a cone (Kern) NS 18,8 and the other as a socket (Hülse) NS 29,2, giving a direct size transition within interchangeable ground-joint assemblies. Such transition pieces support flexible set-ups when vessels, condensers, adapters or other jointed components must be linked despite mismatched NS dimensions. The article is supplied as a single piece and belongs to the group of laboratory transition and reducing-joint accessories. This transition piece from manufacturer Starke addresses routine configuration needs in chemical, analytical and preparative work where standard ground-joint geometry is employed. Bridging NS 18,8 and NS 29,2 helps maintain a continuous jointed pathway without improvised couplings. It is intended for integration into existing jointed apparatus trains whenever a defined step between these two nominal sizes is required in research, teaching or quality-control laboratories.

Questions about Transition pieces Core NS 18.8 - Sleeve NS 29.2
What is this article?
Transition pieces Core NS 18.8 - 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.
