Description
Standing flask, borosilicate glass, white graduated, 500 ml with NS 24/29 joint is a heat-resistant laboratory vessel for heating, distillation and general chemical applications. Produced from durable borosilicate glass in accordance with DIN EN ISO 4797, this standing flask (round-bottom flask with standard ground joint) features a thick wall, heavy base and reinforced rim that help prevent breakage during cleaning and transport. Perfectly ground NS necks with a smooth interior provide a secure, leak-tight seal when used with compatible stoppers or adapters. Volume graduations and markings are applied in white enamel for durable, easy-to-read identification. Supplied without stopper, the 500 ml flask from manufacturer ISOLAB Laborgeräte fits standard laboratory glassware setups in research, education and quality-control environments. Its robust build supports repeated thermal stress and routine handling, while the NS 24/29 joint ensures straightforward connection to condensers, adapters and other ground-joint components. Well suited to reflux, sample preparation and related workflows that call for a stable, graduated standing flask of medium capacity.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - flat bottom - glass - clear - NS neck - 500 ml - NS24/29
What is this article?
flask - flat bottom - glass - clear - NS neck - 500 ml - NS24/29 is the article on this page. Luminix Health distributes ISOLAB 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.
