Beschreibung
DURAN® flat flange lid with centre neck NS 45/40 is a borosilicate glass 3.3 cover for DN 150 flat flange vessels used as large-volume reaction systems. Flat flange vessels consist of a base and lid secured by a clamping ring; a gasket or ground-joint grease prevents the ground surfaces from seizing. Standard ground joints in the lid enable combination with additional components such as dropping funnels and stirrer shafts. The vessels are well suited to preparative operations including general reactions, distillations, evaporations and drying involving solid and viscous substances. Geometry and substantial wall thickness support safe working under pressure and vacuum. From manufacturer Duran/DWK Life Sciences, this lid features a centre neck NS 45/40 and a dense seal via the standard ground joint. Typical applications cover chemically and thermally demanding processes and safe operation under pressure or vacuum, with a maximum operating overpressure at 250 °C. The DURAN® flat flange design provides a robust alternative to round-bottom flasks for larger preparative laboratory work.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about DURAN® Flat Flange Lid, with centre neck
What is this article?
DURAN® Flat Flange Lid, with centre neck is the article on this page. Luminix Health distributes DWK Life Sciences 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.
