Description
Duran® DN 150 flat flange lid with NS 29/32 centre neck is a laboratory glassware lid for larger flat-flange vessels and suction-bottle systems. The component provides a DN 150 flat flange mating face together with a central NS 29/32 ground joint, allowing standard taper glassware such as adapters or condensers to be connected above the vessel. Supplied as one piece with a weight of 0,755 kg, it suits laboratory assemblies that need a broader flange seal while retaining a common centre-neck standard. This flat flange lid from manufacturer DWK Life Sciences is part of the Duran® glassware line and supports filtration, vacuum and multi-neck configurations used with suction bottles and related seals. The DN 150 size addresses mid-to-larger vessel formats, and the NS 29/32 centre neck keeps compatibility with everyday jointed accessories. It fits laboratory glass, vessels and consumables applications involving Büchner funnels, suction bottles and sealing components, and is offered as a single unit for new builds or replacement of existing lids in standardised glass setups.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

What is this article?
Duran® DN 150 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.
