Description
DURAN® Safety Ground Joint, Cone with Collar NS 19/26 is a precision laboratory glass component engineered for secure, reliable connections in scientific apparatus. The cone incorporates an additional integrally moulded glass collar and ring that actively prevents unintentional loosening of the ground-joint seal, delivering enhanced protection when working with hazardous substances or under pressure differentials. This same design also simplifies the controlled release of seized joints, substantially reducing the risk of glass breakage and related laboratory hazards. Offered as a single piece with a net weight of 0,024 kg and gross weight of 0,025 kg, the article provides a dense, standardised NS 19/26 ground-joint closure suitable for further processing into complete glass assemblies. Manufactured by Duran/DWK Life Sciences, these safety cones integrate seamlessly into apparatus requiring elevated safety standards and complement established KECK™ joint-securing systems. Typical applications include construction of glassware for chemical handling under demanding conditions, pressure-difference work, and any setup where unintentional disconnection must be avoided while still allowing controlled disassembly when required.

Questions about DURAN® Safety Standard Ground Cone, with collar
What is this article?
DURAN® Safety Standard Ground Cone, with collar 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.
