Description
Flat-bottom flasks in DURAN® borosilicate glass with a narrow neck and 50 ml nominal capacity are standard laboratory vessels for heating, mixing, storage, and general wet-chemistry work on stable surfaces. The flat base allows secure placement on hotplates, stirrers, and benches without a supporting ring, while the narrow neck reduces evaporation and facilitates stoppering or connection to simple apparatus. These flasks form part of the classic round-flask and laboratory-glassware range used across teaching, research, and quality-control laboratories. They are supplied from manufacturer DWK Life Sciences as DURAN® narrow-neck flat-bottom flasks in a convenient multipack. The pack contains 10 pc(s) with a total weight of approximately 0,473 kg, supporting routine stocking of small-volume glassware. Typical applications include preparation of solutions, gentle reflux setups where geometry permits, sample holding, and intermediate reaction steps that benefit from a stable footprint. Select the 50 ml size when working with limited sample volumes or when multiple parallel preparations are required. As with all laboratory glass, inspect for damage before thermal or vacuum use and follow established glassware handling practice. The combination of DURAN® quality, narrow neck, and flat bottom makes this format a versatile consumable for everyday laboratory glass inventories.

Questions about Flat-bottom flasks, DURAN®, narrow neck, 50 ml, 10 unit(s)
What is this article?
Flat-bottom flasks, DURAN®, narrow neck, 50 ml, 10 unit(s) 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.
