Description
Flat flange lid DN 100 MH NS 29/32 is a multi-neck laboratory lid for flat-flange reaction vessels, produced in borosilicate glass. It combines one central ground joint neck NS 29/32, two side necks NS 29/32 inclined at 15°, and one straight side neck NS 14/23, giving flexible access for condensers, dropping funnels, temperature probes and stirrer shafts on a DN 100 flange. The flat flange interface supports a secure, even seal with matching vessels and clamps, which is essential for synthesis, reflux and multi-port reagent addition. Net weight is 0,472 kg. This configuration from manufacturer Witeg suits organic chemistry, pharmaceutical process development and pilot-scale work where several simultaneous connections are required. Borosilicate glass provides strong thermal-shock resistance and broad chemical durability toward common laboratory solvents and reagents. The lid is supplied as a single piece and integrates readily into existing DN 100 flat-flange glass assemblies used in research and industrial laboratories.

Questions about Lids flat flange LF 100 CN ST 29/32
What is this article?
Lids flat flange LF 100 CN ST 29/32 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.
