Description
DURAN® cone with drain, ground, NS 24/29 is a specialised laboratory glass joint component produced from borosilicate glass 3.3 for integration into glass apparatus and devices. These cones with drain meet DIN 12249 Form G. The drain serves as a drip ring that prevents liquid from running down the vessel inner wall; it is typically cut at an angle and fused, keeping media clear of the greased ground joint surface and allowing clean run-off without wetting the joint. The additional drain can likewise act as an attachment site for extensions for diverse purposes, for instance as an inlet tube. Key advantages are the ground finish with finer grind quality and reduced roughness depth together with a tight closure through the standard ground joint. Available as one piece with a net weight of 0,035 kg, this glass article for further processing from manufacturer Duran/DWK Life Sciences is intended for installation in laboratory glassware systems. It supports secure NS joints and controlled liquid drainage wherever reliable apparatus construction and joint integrity are required.

Questions about DURAN® Standard Cone with tip, finished
What is this article?
DURAN® Standard Cone with tip, 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.
