Description
Flat flange lid DN 100 MH NS 45/40 is a borosilicate-glass multi-neck lid intended for DN 100 flat-flange reaction systems. The layout comprises one large central ground joint neck NS 45/40, two side necks NS 29/32 set at 15°, and one straight side neck NS 14/23. This arrangement supports larger central fittings such as stirrer bearings or wide condensers while still providing angled and straight ports for additional apparatus. The DN 100 flat flange ensures a stable, clampable seal with compatible vessels. Net weight is 0,502 kg. Offered by manufacturer Witeg, the lid is well suited to organic synthesis, scale-up studies and multi-component reaction setups in research and development laboratories. Borosilicate glass delivers the thermal and chemical resistance expected for routine and demanding laboratory chemistry. Supplied as one piece, it fits standard DN 100 flat-flange glassware trains used for reflux, distillation and controlled reagent addition.

Questions about Lids flat flange LF 100, with center nec
What is this article?
Lids flat flange LF 100, with center nec 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.
