Description
Flat-bottom flask with standard ground joint NS 29/32 is a laboratory vessel made from borosilicate glass LBG 3.3 with a nominal volume of 2 l (2000 ml). The flat base gives a stable footprint on hotplates, stirrers and benches, supporting heating, mixing and reaction work where a standing flask is preferred. The NS 29/32 ground joint provides a standardised, interchangeable connection to condensers, adapters, stoppers and other jointed glassware in common laboratory assemblies. Fabricated from borosilicate glass 3.3, the flask combines thermal resistance with broad chemical durability for aqueous media and many organic solvents used in routine preparative and analytical work. This pack contains 2 pieces and is offered from manufacturer Labbox for teaching, research and quality-control environments. With a pack net weight of 1,505 kg, the set suits distillation setups, reflux reactions, sample preparation and general wet-chemistry workflows that need a large working volume together with a secure flat-bottom geometry rather than a round-bottom design.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask, flat bottom, LBG 3.3, mouth 29/32, 2000 ml, 2 pcs
What is this article?
Boiling flask, flat 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.
