Description
DURAN® cone with drain, ground, NS 45/40 is a precision laboratory glass joint component manufactured from borosilicate glass 3.3. These cones with drain correspond to DIN 12249 Form G and incorporate an integrated drain that functions as a drip ring. The drain prevents liquid from running down the inner wall of the vessel; it is typically cut obliquely and fused. This arrangement ensures that media do not contact the greased ground joint surface while allowing clean drainage or outflow without wetting the joint itself. The finely ground finish delivers reduced surface roughness for a reliable, tight seal via the standard ground joint. The additional drain can also serve as an attachment point for extensions serving various purposes, for example as an inlet tube. Intended as a glass article for further processing, the component is designed for incorporation into glass apparatus and devices. Offered by manufacturer Duran/DWK Life Sciences in a convenient single-piece pack, it supports flexible assembly of laboratory setups requiring controlled liquid handling at the joint. Net weight is 0,089 kg and gross weight 0,089 kg, making it a practical choice for scientific glassware constructions.

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.
