Description
Flat-bottom flask, borosilicate glass, white graduated, 100 ml, NS 19/26, without stopper is a standing laboratory flask for everyday heating, reaction and volume-handling tasks. It is produced from heat-resistant, durable borosilicate glass conforming to DIN EN ISO 4797. A thick wall, heavy base and reinforced rim help prevent breakage during cleaning and transport, while the perfectly ground NS 19/26 neck with smooth interior provides a secure, leak-tight connection to matching ground-joint components. White enamel quantity markings and inscriptions are printed for lasting visibility and practical approximate volume control. This single-piece flask from manufacturer ISOLAB Laborgeräte is supplied without stopper and is intended for general laboratory use where a stable flat-bottom vessel with a larger standard joint is preferred. The combination of robust borosilicate construction and standardised NS geometry makes it a reliable choice for chemistry benches, sample work-up and teaching laboratories that rely on interchangeable ground-joint glassware.
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 - 100 ml - NS19/26
What is this article?
flask - flat bottom - glass - clear - NS neck - 100 ml - NS19/26 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.
