Description
Round-bottom flask with standard ground joint NS 29/32 is a 2000 ml laboratory vessel made from borosilicate glass LBG 3.3, supplied as a pack of 2 pieces. The two-litre capacity and large NS 29/32 joint are intended for preparative-scale reactions, distillations and solvent collection where secure, interchangeable ground-glass connections are essential. Borosilicate glass 3.3 delivers the thermal and chemical resistance needed for prolonged heating, reflux and cooling under ordinary laboratory conditions. Nominal volume is 2 l; pack net weight is 1,370 kg. From manufacturer Labbox, these LBG round-bottom flasks function as reaction flasks, distillation flasks or receiving flasks in synthetic chemistry, process development and teaching environments that standardise on NS 29/32 glassware. Consistent joint sizing and robust construction help maintain reliable seals with condensers, adapters and other modular components across multi-step workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 29/32, 2000 ml, 2 pcs
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 29/32, 2000 ml, 2 pcs is the article on this page. Luminix Health distributes Labbox 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.
