Description
Flat-bottom flask 500 ml NS 29/32 is a clear laboratory flask manufactured from borosilicate glass 3.3. It offers a nominal volume of 0,5 l, an outer diameter of 105 mm and a height of 165 mm, combined with a medium neck finished to the standardised NS 29/32 ground joint. The flat base provides stable placement on hotplates, stirrers or benches, while the precision joint ensures leak-tight connection to condensers, adapters and other common ground-joint components used in synthesis and distillation. Produced by Witeg, the flask delivers the thermal-shock resistance and chemical durability characteristic of borosilicate glass 3.3, making it suitable for boiling, reflux, sample preparation and general wet-chemistry work. Clear walls allow continuous visual monitoring of reactions, colour changes and phase behaviour. Supplied in packs of 10 pieces, these flasks integrate readily into standard laboratory glassware sets where dimensional consistency and reliable joint geometry are required for everyday research and quality-control applications.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flat bottom flask 500 ml ST 29/32
What is this article?
Flat bottom flask 500 ml ST 29/32 is the article on this page. Luminix Health distributes Witeg 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.
