Description
Flat-bottom flask DURAN® with narrow neck is a large-capacity laboratory vessel designed for preparative work, heating, and storage of liquids on a stable base. With a nominal volume of 6000 ml, this single-piece flask suits bulk media preparation, solvent handling, and general wet-chemistry workflows where a flat standing surface is preferred over a round bottom. Manufactured from DURAN® borosilicate glass by DWK Life Sciences, it combines chemical resistance with good thermal performance for routine laboratory use. The narrow neck supports controlled pouring, stoppering, and connection to simple closures or adapters while limiting evaporation. Supplied as 1 pc, the unit has a stated weight of 1,650 kg, reflecting the robust wall thickness expected of large glassware. Typical applications include buffer and reagent preparation, temporary holding of process liquids, and bench-scale operations that require a free-standing flask without a heating mantle or cork ring. The clear glass body allows visual monitoring of fill level and contents during use.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flat-bottom flask, DURAN®, narrow neck, 6000 ml, 1 unit(s)
What is this article?
Flat-bottom flask, DURAN®, narrow neck, 6000 ml, 1 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
