Description
DURAN® flat flange lid DN150 is a four-neck glass lid for larger flat flange vessels used in laboratory reaction, distillation and process chemistry. It features a centre neck NS 29/32 and three inclined side necks, each NS 29/32, providing consistent ground-joint interfaces across the cover. The DN150 flange size addresses bigger reactor bodies where multi-port access is needed for stirrers, condensers, dosing equipment and measurement probes. Flat flange construction supports secure coupling to compatible DURAN® vessel systems in synthesis, extraction and scale-oriented workflows. Supplied as a single unit with a weight of 0,950 kg, the lid fits dedicated glass trains and modular assemblies. Offered by manufacturer DWK Life Sciences, this DURAN® component is selected when a DN150 vessel must carry four NS necks with uniform NS 29/32 side joints. Laboratories apply such lids for controlled multi-neck operation during heating, agitation, addition and vapour handling. Choose this DN150 four-neck lid when your apparatus requires a centre NS 29/32 plus three inclined NS 29/32 side necks on a flat flange reactor.

Questions about Flat flange lid DURAN® 4 necks with NS centre neck, 3 inclined side necks
What is this article?
Flat flange lid DURAN® 4 necks with NS centre neck, 3 inclined side necks 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.
