Description
DURAN® Cone, DG-ground, NS 24/29 is a conical ground joint core manufactured from borosilicate glass 3.3 for use in laboratory glass apparatus. The diamond-ground surface provides a coarser grind quality with greater roughness depth, making this component a cost-effective alternative to standard ground DURAN® cones that do not conform to DIN 12249. Forming a rigid, self-supporting connection with a matching socket, the article is intended for further processing and integration into glass assemblies and devices. Ground joint connections should be used with joint grease or PTFE sleeves to ensure a reliable seal, while KECK™ conical joint clamps provide secure retention of the assembled joint. Supplied as a single piece with a net weight of 0,035 kg, this glass component from manufacturer Duran/DWK Life Sciences delivers a dense closure through the standardised ground joint geometry. Typical applications include construction and assembly of laboratory glassware where economical DG-ground joints meet practical performance needs without requiring full DIN compliance.

Questions about DURAN® Standard Cone diamond-ground
What is this article?
DURAN® Standard Cone diamond-ground 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.
