Description
Flat-bottom flask, wide neck, 1000 ml, DURAN® is a borosilicate glass 3.3 laboratory vessel for heating, mixing, storage and general wet-chemistry work on a stable base. The wide-neck design with beaded rim eases filling, cleaning and insertion of stirrers or funnels, while the nominal volume of 1000 ml (1 l) supports medium-scale preparations. External dimensions include a neck outer diameter of 50 mm, a body outer diameter of 131 mm and a height of 190 mm, giving a compact footprint for hotplates, stands and storage shelves. DURAN® glass offers the thermal and chemical resistance expected of borosilicate 3.3 in routine laboratory use. Net weight is 0,296 kg per flask. This wide-neck flat-bottom flask from manufacturer Witeg is packed in units of 10 pc(s), making it practical for stocking teaching laboratories, quality-control benches and research groups that need consistent glassware geometry. The combination of flat base, wide opening and defined dimensions supports reproducible workflows for dissolution, reaction setup and sample holding without specialised ground joints.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, flat bottom, wide neck, 1000 ml,
What is this article?
Flasks, flat bottom, wide neck, 1000 ml, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
