Description
DURAN® round-bottom flask NS 29/32 with 100 ml nominal volume is a versatile laboratory vessel made from borosilicate glass 3.3. Round-bottom flasks are widely used in the laboratory because of their broad range of applications. Contents can be heated evenly with heating mantles or liquid baths, or cooled in cold baths; point heating or cooling should be avoided. The spherical geometry also makes the flask suitable for vacuum work, provided the glass surface is free from impacts and deep scratches. The precision ground joint ensures a tight, accurate connection to other ground-glass components such as columns, thermometers and dropping funnels. Fired-on white printing remains permanently legible, and the flask can be closed with glass or plastic stoppers. Typical uses include distillation, extraction, evaporation of liquids, drying of materials, heating and mounting on stands. This single-neck flask from manufacturer Duran/DWK Life Sciences offers uniform heat distribution and reliable sealing for everyday laboratory procedures. Nominal volume is 0,1 l.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about DURAN® Round Bottom Flask, with standard ground joint
What is this article?
DURAN® Round Bottom Flask, with standard ground joint is the article on this page. Luminix Health distributes DWK Life Sciences 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.
