Description
Flat flange sealing ring DURAN® DN200 is a silicone/FEP seal designed for larger flat-flange laboratory glass components. The DN200 format fits matching vessels and covers used in distillation, extraction and preparative reaction work. A resilient silicone body combined with an FEP contact layer balances conformability and chemical resistance at the flange interface. The ring is supplied as a single piece for installation or replacement on DURAN®-compatible flat-flange assemblies. This component from manufacturer DWK Life Sciences serves laboratories that standardise on DN200 connections and need a defined sealing element for glass systems. It supports maintenance of reactors, multi-neck flasks and process glassware where a secure flange joint is essential. Proper alignment of the sealing ring helps limit vapour or liquid loss during heating, stirring or reduced-pressure operations in research and scale-up environments.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Flat flange sealing ring, DURAN®, DN200,, Silicone/FEP, 1 unit(s)
What is this article?
Flat flange sealing ring, DURAN®, DN200,, Silicone/FEP, 1 unit(s) 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 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.
