Description
Flat flange lid DN60 GL25 is a borosilicate glass cover engineered for laboratory vessels fitted with DN 60 flat flanges. The lid carries one central screw-thread neck GL 25, two side necks GL 18 inclined at 15°, and one straight parallel side neck GL 14. This arrangement allows secure attachment of probes, condensers, addition funnels or gas lines via GL thread adapters while keeping the working space accessible. Made from borosilicate glass by Witeg, the component delivers the chemical durability and thermal performance required for synthesis, process development and analytical work. The combination of a central GL 25 port with angled and parallel side necks supports flexible multi-port configurations without the need for ground-joint greasing. Supplied as a single piece with a net weight of 0,22 kg, the lid fits standard DN 60 flat-flange systems used in organic chemistry, pharmaceutical laboratories and pilot-scale reaction setups.

Questions about Lids flat flange, DN 60, with center nec
What is this article?
Lids flat flange, DN 60, 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 Matériel de laboratoire.
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.
