Beschrijving
Flat flange lid DN 100 is a laboratory glassware cover engineered for flat-flange reaction vessels requiring mixed neck sizes. The lid presents a flange outer diameter of 138 mm, a centre neck NS 29/32, one straight side neck NS 14/23 and two angled side necks NS 29/32. This arrangement allows a main stirrer or condenser on the centre joint while the smaller straight NS 14/23 port accommodates thermometers, probes or narrow addition lines, and the angled NS 29/32 necks free space for bulkier accessories. Supplied as a single piece with a net weight of 0,1 kg from manufacturer Witeg, the component supports organic chemistry, process research and educational setups that rely on DN 100 flat-flange systems. Standard ground-joint dimensions ensure compatibility with common laboratory glassware, facilitating rapid assembly and secure sealing under atmospheric or vacuum conditions. The mixed-neck layout is particularly useful when both large and small ports are needed on one compact lid without exchanging the vessel.

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 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.
