Description
Round-bottom flask with standard ground joint NS 14/23 and a nominal volume of 50 ml is a compact laboratory vessel for heating, reaction work and small-scale distillation setups. Manufactured from borosilicate glass 3.3 (LBG 3.3), the flask combines thermal shock resistance with chemical durability suited to routine organic and analytical procedures. The spherical body promotes even heat distribution when used with heating mantles or oil baths, while the NS 14/23 joint ensures reliable, interchangeable connections to condensers, adapters and other ground-joint glassware. With a net weight of 0,022 kg, the single piece is easy to handle on the bench or in a fume hood. This Labbox flask is intended for distillation, reflux, solvent recovery and general synthesis where a 50 ml working volume is required. Clear wall thickness and the standardised joint geometry support reproducible assembly of multi-neck or single-neck apparatus. Suitable for teaching laboratories as well as research and quality-control environments that rely on classic borosilicate round-bottom flasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 14/23, 50 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 14/23, 50 ml 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.
