Description
Round-bottom flask 500 ml NS 29/32 is a clear laboratory flask made from borosilicate glass 3.3 for distillation, collection, heating and general apparatus work. It offers a nominal volume of 0,5 l and a single medium neck finished with standard ground joint NS 29/32, ensuring secure connection to condensers, adapters and complementary glassware. External diameter is 105 mm and overall height is 170 mm, giving a compact geometry suited to bench-top stands and heating setups. Borosilicate glass 3.3 provides the chemical resistance and thermal stability expected in routine laboratory practice, while the clear-glass finish allows continuous observation of contents. Supplied in packs of 10 pieces with a net weight of 0,164 kg per flask, these vessels from manufacturer Witeg serve as round-bottom, ground-joint, distillation or receiving flasks in research, quality-control and teaching laboratories. Compatibility with standard NS 29/32 joints supports straightforward integration into existing assemblies without specialised adapters.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 500 ml ST 29/32
What is this article?
Round 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.
