Description
Flat flange lid DN 150 is a laboratory glassware cover designed for vessels with a DN 150 flat flange connection. The lid features a flange outer diameter of 184 mm and a centre neck with ground joint NS 29/32, allowing straightforward attachment of condensers, dropping funnels, stirrers or other standard joint accessories. With a net weight of 0,828 kg, this single-piece component is suited to reaction setups, distillation assemblies and multi-neck reactor configurations commonly used in synthetic and preparative chemistry. Manufactured by Witeg, the flat flange lid provides a stable, well-defined interface for DN 150 glass apparatus and supports modular build-up of laboratory glass systems. The centre neck NS 29/32 offers a widely used joint size for flexible equipment combinations. Ideal for research and process laboratories that rely on flat-flange reactor lids with a single central ground joint for controlled reactions and sample handling.

Questions about Lid flat flange DN 150
What is this article?
Lid flat flange DN 150 is the article on this page. Luminix Health distributes Witeg 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.
