DURAN® flat flange lid with centre neck NS 29/32 is a precision-engineered cover for DN 200 flat flange reaction vessels used in preparative laboratory work. Manufactured from borosilicate glass 3.3, the lid forms the upper half of a two-part flat flange system that is secured with a clamping ring; a gasket or ground-joint grease prevents the ground surfaces from seizing. The centre neck with standard ground joint NS 29/32 accepts additional components such as dropping funnels, stirrer shafts or condensers, enabling flexible reactor configurations. Geometry and substantial wall thickness make the assembly pressure- and vacuum-resistant, supporting safe operation under overpressure or vacuum at temperatures up to 250 °C. Flat flange vessels of this type are well suited to general reactions, distillations, evaporations and drying processes involving solid or viscous materials. Supplied as a single piece from manufacturer Duran/DWK Life Sciences, the lid offers a durable, chemically resistant solution for demanding chemical and thermal workflows in research and production laboratories.

Questions about DURAN® Flat Flange Lid, with centre neck
What is this article?
DURAN® Flat Flange Lid, with centre neck is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labmateriaal.
A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
