Description
Round-bottom flask, wide neck, 20000 ml, DURAN® is a high-capacity single-neck laboratory flask fabricated from borosilicate glass 3.3 for demanding volume-intensive work. Its wide neck and beaded rim facilitate loading, transfer and thorough cleaning, and the spherical base supports even heating and stirring in large-scale distillation, reaction or collection assemblies. Nominal volume is 20 l; outer neck diameter is 89 mm, body outer diameter 345 mm and overall height 520 mm. Net weight is 4,633 kg. Available as one piece from manufacturer Witeg, this DURAN® flask brings borosilicate 3.3 durability to round-bottom geometries used in preparative chemistry and process laboratories. It is suited to round-bottom, distillation and receiving-flask roles whenever a 20000 ml wide-neck vessel with documented outer dimensions and height is required for safe mounting and thermal processing.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, round bottom, wide neck, 20000 m
What is this article?
Flasks, round bottom, wide neck, 20000 m is the article on this page. Luminix Health distributes Witeg 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.
