Description
Standing flask, borosilicate glass, white graduated, 50 ml, NS 14/23, without stopper is a flat-bottom laboratory flask with a standard ground joint for secure connection to stoppers, condensers or adapters. Manufactured from heat-resistant, durable borosilicate glass in accordance with DIN EN ISO 4797, the vessel features a thick wall, heavy base and reinforced rim that help prevent breakage during cleaning and transport. The precisely ground NS 14/23 neck has a smooth interior to ensure a leak-tight seal when mated with matching joints. Volume graduations and inscriptions are printed in white enamel for clear readability under laboratory lighting. Supplied without a stopper, the 50 ml flask is ready for integration into existing glassware sets. This standing flask from manufacturer ISOLAB Laborgeräte is suited to heating, mixing, reaction and storage tasks in chemical, pharmaceutical and teaching laboratories. The robust construction and standardised joint make it a practical choice for routine analytical and preparative work where a stable, graduated borosilicate vessel is required.

Questions about flask - flat bottom - glass - clear - NS neck - 50 ml - NS14/23
What is this article?
flask - flat bottom - glass - clear - NS neck - 50 ml - NS14/23 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.
