Description
Duran® DN 150 flat flange lid with NS 45/40 centre neck is a laboratory glassware component intended for use with suction bottles and related filtration assemblies. The lid is specified for a DN 150 flat flange connection and provides a central ground joint neck in NS 45/40 format, supporting secure coupling of adapters, condensers, or other jointed glassware in vacuum filtration and related workflows. Supplied as a single piece with a stated weight of 0,800 kg, it fits laboratory setups that rely on standardised flat-flange vessels for solid–liquid separation, Büchner-type filtration trains, and general suction work. The Duran® design language emphasises dimensional compatibility with common DN flange systems used across analytical and preparative laboratories. This flat flange lid from manufacturer DWK Life Sciences is positioned among laboratory glass vessels and consumables for filtration and suction applications, where a defined centre neck and flange size help maintain a reproducible apparatus layout. It is offered as one unit for direct integration into existing DN 150 flat-flange bottle configurations without additional claimed performance attributes beyond the stated geometry and pack presentation.

Questions about Duran® DN 150 flat flange lid,, NS 45/40 centre neck, 1 unit(s)
What is this article?
Duran® DN 150 flat flange lid,, NS 45/40 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 Matériel de laboratoire.
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.
