Beschrijving
Flat flange lid DN 120 is a laboratory glassware cover for flat-flange reaction and process vessels with nominal diameter DN 120. The flange has an outer diameter of 158 mm and the lid is fitted with a centre neck NS 29/32, providing a standard ground-joint interface for condensers, stirrer guides or other apparatus. Supplied as a single piece, this component is intended for setups that require a plain centre neck without additional side necks. The lid from manufacturer Witeg supports assembly of multi-neck configurations on compatible flat-flange vessels used in synthesis, distillation and general laboratory process work. With a net weight of 0,682 kg, it is a substantial glass part suited to stable mounting on matching DN 120 flanges. Laboratories working with planschliff or flat-flange reactor systems can use this lid wherever a simple centre-neck geometry is specified. Dimensions and joint sizes follow the stated DN 120 and NS 29/32 values for straightforward matching to existing glassware trains.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Lid flat flange DN 120
What is this article?
Lid flat flange DN 120 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labmateriaal.
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.
