Beschreibung
Flat flange lid DN 100 is a multi-neck laboratory glassware closure for flat-flange reaction vessels and reactors. It combines a flange outer diameter of 138 mm with a centre neck NS 29/32 and three angled side necks NS 29/32, giving convenient multi-port access for stirrers, reflux condensers, thermometers, dropping funnels and gas inlets on a single DN 100 plane flange. The angled side necks improve clearance for bulky accessories and support simultaneous connection of several standard ground-joint components while maintaining a reliable seal. Supplied as one piece with a net weight of 0,492 kg from manufacturer Witeg, this lid suits organic synthesis, process development, scale-up work and teaching laboratories that use interchangeable flat-flange apparatus. Ground-joint geometry matches common laboratory glassware standards, enabling quick assembly under atmospheric or reduced-pressure conditions. The robust multi-neck layout is well suited to chemical reaction setups that require flexible instrumentation without changing the vessel body.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Lid flat flange DN 100
What is this article?
Lid flat flange DN 100 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Laborbedarf.
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.
