Conical joint core NS 5/13 is a standardized laboratory ground-joint component produced to DIN 12249. This male core taper in the NS 5/13 size provides a defined conical interface for assembling modular laboratory apparatus in chemical synthesis, analytical work, and general research setups. The DIN-conform geometry supports interchangeable mating with matching sockets of the same nominal size, helping laboratories build, extend, or replace glassware trains with consistent fit. Offered as a single piece, the joint is intended for routine assembly tasks where dimensional conformity to the European NS series is essential. Components of this type from manufacturer Schlee are used wherever secure, reusable conical connections are preferred for distillation, reaction, transfer, or teaching apparatus. NS 5/13 identifies the nominal diameter and length class widely applied in European laboratory practice, simplifying inventory and cross-compatibility between multi-piece systems. Suitable for educational, industrial QC, and research environments that depend on standardized conical joints for reliable, tool-free coupling of laboratory components without inventing non-specified materials or performance grades.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Conical joints according DIN 12249, cone NS 5/13
What is this article?
Conical joints according DIN 12249, cone NS 5/13 is the article on this page. Luminix Health distributes Schlee for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labmateriaal.
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.
