Description
Duran® DN 120 flat flange lid with NS 29/32 centre neck is a laboratory glassware component for compatible flat flange vessels and suction systems. The lid combines a DN 120 flange interface with a central ground joint neck in the widely used NS 29/32 format, enabling secure connection of condensers, dropping funnels, adapters, or other standard joint accessories. Produced by DWK Life Sciences under the Duran® brand, it supports filtration assemblies, reaction setups, and vacuum applications where a robust flat flange closure is required. Supplied as one piece, it integrates into existing DURAN® flat flange vessel configurations used in chemical, pharmaceutical, and academic research laboratories. The NS 29/32 centre neck accommodates common laboratory joints while helping maintain a sealed working environment. Suitable for routine glassware layouts, this flat flange lid completes vessel systems for distillation, extraction, suction filtration, and related process steps. Accurate DN 120 sizing ensures correct pairing with matching flange bodies, gaskets, and clamps for reliable laboratory performance across standard bench workflows.

Questions about Duran® DN 120 flat flange lid,, NS 29/32 centre neck, 1 unit(s)
What is this article?
Duran® DN 120 flat flange lid,, NS 29/32 centre neck, 1 unit(s) 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 Labware.
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.
