Flat-bottom flask, wide neck, 100 ml, DURAN® is a standing laboratory flask manufactured from borosilicate glass 3.3 for routine chemical handling, sample preparation and general wet-lab work. With a nominal volume of 0,1 l, the wide-neck design incorporates a beaded rim that aids secure gripping and seating of stoppers or covers. Key dimensions include a neck outer diameter of 34 mm, a flask outer diameter of 64 mm and an overall height of 105 mm, giving a compact, stable footprint on the bench. The flat base allows free-standing use without a separate support ring. Produced in DURAN® glass and offered by manufacturer Witeg, the vessel benefits from the thermal shock resistance and chemical durability associated with borosilicate glass 3.3. The wide neck simplifies filling, emptying and cleaning and improves access for spatulas, funnels or sampling tools. Net weight is 0,06 kg per flask. Suitable for reagent holding, mixing and everyday laboratory procedures where a transparent, robust glass container is required. Supplied in packs of 10 pieces for convenient laboratory stock replenishment.

Questions about Flasks, flat bottom, wide neck, 100 ml,
What is this article?
Flasks, flat bottom, wide neck, 100 ml, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
