Description
Flat-bottom flask 2000 ml NS 29/32 is a clear laboratory standing flask designed for larger-scale heating, mixing and reaction work. It provides a nominal volume of 2 l and a standard ground joint NS 29/32 for reliable connection to condensers, adapters and complementary jointed apparatus. Outer diameter measures 166 mm and height 245 mm, offering a stable base and practical working height for bench and hotplate use. The medium-neck design facilitates charging and cleaning while maintaining joint compatibility. Fabricated from borosilicate glass 3.3, the flask delivers strong chemical resistance, thermal stability and optical clarity for monitoring contents throughout procedures. Supplied in packs of 10 pieces from manufacturer Witeg, this flat-bottom flask supports synthesis, distillation, sample preparation and process development in research and industrial laboratories. The flat base ensures secure placement on heating surfaces, and the precision-ground NS 29/32 joint helps maintain tight seals under vacuum or vapour load in multi-component glassware assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flat bottom flask 2000 ml ST 29/32
What is this article?
Flat bottom flask 2000 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.
