Description
Flat-bottom flask with narrow neck NS, 3000 ml, produced from borosilicate glass LBG 3.3, is intended for large-volume laboratory operations such as heating, blending and temporary storage of solutions and reaction mixtures. Its flat base rests securely on hotplates, magnetic stirrers and benches, while the narrow neck with standard ground joint (NS) allows controlled pouring and fits customary laboratory closures and adapters. Borosilicate glass 3.3 supplies the chemical resistance and thermal-shock tolerance needed for daily analytical and preparative tasks. Available as a single piece from manufacturer Labbox, this flask suits teaching laboratories, quality-control stations and research groups handling multi-litre batches. Nominal volume is 3 l, practical for stock solutions, media preparation and process samples. The LBG designation refers to the borosilicate glass composition of the series. Typical use includes aqueous systems, organic solvents within glass compatibility limits and general wet-chemistry workflows where a free-standing large flask is preferred.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask, flat bottom, narrow neck, 3000 ml, LBG 3.3
What is this article?
Boiling flask, flat bottom, narrow neck, 3000 ml, LBG 3.3 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.
