Description
Round-bottom flask, wide neck, 1000 ml, DURAN® is a single-neck laboratory flask for heating, distillation, reaction and collection work that benefits from a spherical body and easy access through a wide opening. It is made from borosilicate glass 3.3 under the DURAN® registered trademark, combining thermal shock resistance with broad chemical durability for routine wet-chemistry use. The vessel has a wide neck with beaded rim, neck outer diameter 50 mm, outer diameter 131 mm and height 200 mm, so it seats securely in standard clamps, heating mantles and supports. Nominal volume is 1 l, making the flask practical for preparative batches, solvent work-up and receiving duties. This wide-neck round-bottom flask from manufacturer Witeg is well suited to teaching labs, research groups and industrial quality-control environments that rely on robust DURAN® glassware for repeated thermal cycling. The open neck geometry simplifies charging solids or viscous media and cleaning between runs. Pack size is 10 pieces, supporting multi-station setups and shared glassware pools without frequent reordering.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, round bottom, wide neck, 1000 ml
What is this article?
Flasks, round bottom, wide neck, 1000 ml 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.
