Description
Round-bottom flask narrow neck 10000 ml DURAN® is a large-capacity single-neck laboratory vessel intended for distillation, reaction chemistry and collection duties. Fabricated from borosilicate glass 3.3 under the DURAN® trademark, it delivers the chemical durability and thermal shock resistance expected in professional laboratory glassware. The Enghals narrow-neck configuration features a beaded rim that aids stopper seating and apparatus connection. With a nominal volume of 10 l, an outer diameter of 279 mm, a height of 380 mm and a neck outer diameter of 65 mm, the flask provides ample working volume while remaining compatible with standard heating mantles and supports. Available as a single piece from manufacturer Witeg, this round-bottom flask is well suited to preparative organic synthesis, solvent recovery, concentration steps and large-scale heating where even heat distribution around the curved base is advantageous. Typical use includes round-bottom, distillation and receiving-flask applications in research, quality-control and teaching laboratories. The combination of DURAN® borosilicate glass 3.3, narrow neck and beaded rim makes it a practical choice for multi-litre workflows that demand reliable glassware performance.

Questions about Flasks, round bottom, narrow neck, 10000
What is this article?
Flasks, round bottom, narrow neck, 10000 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.
