Description
Flat flange beaker DURAN® DN120 is a laboratory glass vessel with groove, offered at a nominal capacity of 1000 ml for demanding wet-chemistry work. The flat-flange geometry supports secure coupling to compatible lids, adapters and process components used in distillation and extraction assemblies, while the groove aids reliable seating of seals and clamps. Built as a DURAN® flat flange beaker, it fits standard laboratory glassware workflows where robust borosilicate vessels are preferred for heating, mixing and intermediate storage of liquids. Categories covering laboratory glass, vessels and consumables place this item among glass components intended for distillation and extraction as well as dedicated flat flange vessel setups. Supplied as a single piece with a unit weight of 1,030 kg, the 1000 ml format suits bench-scale preparations and pilot transfers without unnecessary bulk. The design from manufacturer DWK Life Sciences integrates cleanly into modular flange systems common in research and quality-control laboratories. Use it wherever a DN120 flat flange interface and grooved sealing face are specified for controlled reaction, reflux or sample handling tasks.

Questions about Flat flange beaker, DURAN®, DN120,, with groove, 1000 ml, 1 unit(s)
What is this article?
Flat flange beaker, DURAN®, DN120,, with groove, 1000 ml, 1 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Beakers, inside Beakers & flasks, in Labware.
A beaker is an open, straight-sided working vessel with a spout. It is for dissolving, heating and pouring. The graduations are a guide, not a volumetric calibration. Low form and tall form differ in stability and in how easily a liquid splashes.
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.
