Description
Cone NS 45/40 DURAN is a precision ground-glass joint cone manufactured to DIN 12249 from DURAN tubing. It features an outer diameter of 40 mm, an overall length of 150 mm and a wall thickness of 2,3 mm, and is produced from borosilicate glass 3.3. The DURAN® material provides the thermal shock resistance and chemical durability expected in laboratory glassware assemblies. Offered as a single piece from manufacturer Witeg, this cone is designed for use in standard ground-joint apparatus where accurate NS 45/40 connections and reliable sealing are required. With a net weight of 0,083 kg, it is suitable for constructing, extending or repairing distillation, reaction and filtration setups in research and industrial laboratories. The defined dimensions and high-quality borosilicate construction ensure dimensional stability and long service life under typical laboratory thermal and chemical conditions.

Questions about ST-cone ST45/40 Duran
What is this article?
ST-cone ST45/40 Duran is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
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.
