Description
DURAN® Safety Ground Joint, Cone with Collar NS 34/35 is a precision-engineered glass cone featuring an integrally formed glass ring collar for enhanced connection security in laboratory glassware. This standard ground joint provides a tight seal while the additional collar design actively prevents unintentional loosening of the joint, particularly valuable when handling hazardous substances or working with pressure differentials. The collar also facilitates safer release of seized connections, thereby reducing the risk of glass breakage and associated hazards during apparatus assembly or disassembly. Supplied as a single piece with a net weight of 0,055 kg and gross weight of 0,064 kg, the component is intended for further processing and integration into glass apparatus and devices. Ideal for installations requiring elevated safety standards, these cones from manufacturer Duran/DWK Life Sciences support reliable performance in complex laboratory setups where secure, leak-tight joints are essential. The NS 34/35 size ensures compatibility with corresponding sockets in modular glass systems used for chemical reactions, distillations, and related processes under demanding conditions.

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.
