Description
DURAN® cones with collar, with drain, NS 29/32 are precision ground joint components intended for modular laboratory glassware assemblies. These male cones feature a collar and an integrated drain and conform to the NS 29/32 standard taper, providing compatibility with corresponding sockets used in larger-scale distillation, reaction and separation apparatus. The collar supplies additional mechanical stability when joining or separating glass parts, while the drain permits controlled liquid removal or sampling directly at the joint. Offered as a single piece within the DURAN® portfolio from manufacturer Duran/DWK Life Sciences, the component is suited to chemical, analytical and teaching laboratories that depend on interchangeable ground-joint systems. It enables flexible construction of apparatus for organic synthesis, solvent processing and general wet-chemistry applications where robust, reusable connections are essential. The NS 29/32 size is commonly selected for medium- to larger-volume glass setups, allowing ready incorporation into existing configurations without the need for special adapters in many standard laboratory workflows.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about DURAN® Cones with ridge, with tip, NS 29/32
What is this article?
DURAN® Cones with ridge, with tip, NS 29/32 is the article on this page. Luminix Health distributes DWK Life Sciences 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.
