Description
DURAN® Long Ground Joint Socket, ground, NS 24/40 is a precision laboratory glassware component fabricated from borosilicate glass 3.3 for demanding vacuum work. The long ground-joint design provides an extended sealing surface that delivers finer grind quality and lower surface roughness, enabling a reliably tight standard-ground-joint closure. Because of the enlarged ground area, these sockets are especially suited to high-vacuum applications and are supplied as glass articles ready for further processing. They are routinely built into custom glass apparatus and laboratory devices where vacuum integrity and chemical resistance are essential. Offered as a single piece with a net weight of 0,05 kg (gross weight 0,055 kg), the component combines mechanical robustness with the thermal and chemical stability expected of borosilicate 3.3. Produced by manufacturer Duran/DWK Life Sciences under the DURAN® trademark, the long socket supports secure, leak-resistant connections in high-vacuum lines, distillation trains and modular glass systems. Its finely ground finish minimises leak paths while remaining fully compatible with standard NS 24/40 joints, making it a practical choice for both research and process-scale glass constructions.

Questions about DURAN® Long Ground Socket, finished
What is this article?
DURAN® Long Ground Socket, finished 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.
