Description
Round-bottom flask, narrow neck NS, 250 ml, LBG 3.3 is a borosilicate laboratory flask for heating, mixing, distillation and preparative reaction work at medium scale. Its spherical body promotes even heat transfer and thorough mixing, while the narrow-neck (Enghals) design reduces solvent loss and provides a secure interface for stoppers or simple adapters. Fabricated from borosilicate glass 3.3, the flask delivers the chemical resistance and thermal-shock performance required in everyday analytical and synthetic chemistry. Supplied by manufacturer Labbox as a twelve-piece pack, each flask has a nominal volume of 250 ml (0,25 l); the pack net weight is 1,630 kg. These attributes suit teaching laboratories, research groups and production-support benches that need reliable mid-volume round flasks on hand. Typical uses include organic synthesis, solvent recovery, concentration steps and service as a receiving or intermediate vessel in multi-piece glass assemblies. LBG 3.3 glass tolerates common laboratory solvents and repeated temperature cycling with heating mantles or baths. The twelve-piece unit quantity supports efficient stock management in shared lab environments where round-bottom flasks are consumed regularly.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Ballon, fond rond, col étroit, 250 ml, LBG 3.3, 12 pièces
What is this article?
Ballon, fond rond, col étroit, 250 ml, LBG 3.3, 12 pièces is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
