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 0,5 l (500 ml). Its flat base stands securely on hotplates, magnetic stirrers and laboratory benches, making it practical for heating, stirring and reaction tasks where a stable footprint is required. The standardised NS 29/32 ground joint ensures reliable, interchangeable coupling to condensers, adapters, stoppers and complementary jointed glassware. Produced from borosilicate glass 3.3, the flask offers thermal resistance and chemical durability suited to aqueous systems and many organic media in everyday laboratory practice. This multipack contains 8 pieces and comes from manufacturer Labbox for teaching laboratories, research groups and quality-control workflows. With a pack net weight of 1,720 kg, the set is convenient for parallel experiments, sample preparation, reflux setups and general wet chemistry when a medium working volume and flat-bottom geometry are preferred over round-bottom flasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Ballon à distiller, fond plat, LBG 3.3, col 29/32, 500 ml, 8 pièces
What is this article?
Ballon à distiller, fond plat, LBG 3.3, col 29/32, 500 ml, 8 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.
