Description
Flat-bottom flask with narrow neck NS, 1000 ml, made from borosilicate glass LBG 3.3, is a stable laboratory vessel for heating, mixing, dissolving and temporary storage of liquids and reaction mixtures. The flat base stands securely on hotplates, stirrers and benches, while the narrow neck with standard ground joint (NS) supports controlled reagent addition and fits common stoppers and adapters. Borosilicate glass 3.3 combines chemical resistance with good thermal-shock behaviour for everyday analytical and preparative work. Offered as a pack of six pieces from manufacturer Labbox, the set suits teaching labs, quality-control benches and research groups that need consistent glassware. Nominal volume is 1 l, convenient for medium-scale preparations and stock solutions. The LBG designation identifies the borosilicate composition used in this series. Typical uses include aqueous media, many organic solvents within glass compatibility limits, recrystallisations and general wet-chemistry workflows where a free-standing flask is preferred over round-bottom designs.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask, flat bottom, narrow neck, 1000 ml, LBG 3.3, 6 pcs
What is this article?
Boiling flask, flat bottom, narrow neck, 1000 ml, LBG 3.3, 6 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.
