Description
Flat-bottom flasks DURAN® with narrow neck and 500 ml capacity are laboratory glass vessels designed for bench-scale work that requires a stable, free-standing form. The flat bottom rests securely on the work surface, which is useful for solution preparation, temporary holding of larger liquid volumes, and procedures where additional flask supports are undesirable. Supplied in a pack of 10 pieces from manufacturer DWK Life Sciences, the set weighs 2,000 kg and suits laboratories that maintain stock of commonly used mid-to-large glassware sizes. Narrow-neck geometry facilitates controlled pouring and helps reduce splash and evaporative loss during handling, while remaining compatible with standard laboratory stoppers and closures. These flasks form part of the established range of round flasks and related laboratory glass vessels employed in teaching, research, and analytical settings. At 500 ml they accommodate larger aliquots, buffer or media batches, and general chemical handling. The multipack keeps DURAN® flat-bottom flasks of this capacity readily available for daily experimental, preparative, and storage-related laboratory workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flat-bottom flasks, DURAN®, narrow neck, 500 ml, 10 unit(s)
What is this article?
Flat-bottom flasks, DURAN®, narrow neck, 500 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.
