Description
Standing flask, borosilicate glass, white graduated, 50 ml with NS 29/32 joint and without stopper serves as a stable vessel for routine laboratory procedures. It is made from heat-resistant, durable borosilicate glass according to DIN EN ISO 4797. Thick walls, a heavy base and a reinforced rim help prevent breakage when cleaning or moving the flask, while the precisely ground standard taper neck with smooth interior promotes a leak-tight seal with matching ground-joint components. Volume graduations and inscriptions are printed in white enamel for lasting clarity. The flat-bottom standing geometry keeps the flask secure on the bench during preparation, mixing or moderate heating. Supplied without stopper in a single-piece pack, this 50 ml graduated flask from manufacturer ISOLAB Laborgeräte provides an NS 29/32 connection suited to common laboratory setups. Its solid build and clear markings support reliable day-to-day use with quality borosilicate 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 - 50 ml - NS29/32
What is this article?
flask - flat bottom - glass - clear - NS neck - 50 ml - NS29/32 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.
