Description
Flat flange sealing ring DURAN® DN150 is a silicone sealing component for flat-flange laboratory glass assemblies. It provides the interface seal on DN150 flat flange vessels used in distillation, extraction, and related glassware setups. The ring is supplied in a pack of 5 pc(s), supporting maintenance and assembly of multiple vessels or spare-part stocking in the laboratory. Silicone construction suits typical laboratory flat-flange connections where a flexible sealing ring is specified for DURAN® systems. Pack weight is 1,000 kg. This DURAN® flat flange sealing ring from manufacturer DWK Life Sciences is intended for glass components in distillation and extraction work and other flat-flange vessel applications. Laboratories select the DN150 size when matching existing flange dimensions on reaction, process, or preparative glassware. The product belongs to the flat flange vessels and glass-components category and is used wherever a defined nominal diameter and silicone seal are required for secure flange closure. It is a straightforward consumable seal for routine assembly and service of DN150 flat-flange laboratory equipment.

Questions about Flat flange sealing ring, DURAN®, DN150,, Silicone, 5 unit(s)
What is this article?
Flat flange sealing ring, DURAN®, DN150,, Silicone, 5 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.
