Description
Round-bottom flask with standard ground joint, GLASSCO, NS 14/23, 50 ml is a compact laboratory flask produced from high-quality borosilicate glass 3.3. The vessel features a precision-ground NS 14/23 joint for leak-tight connection to small condensers, adapters and other ground-joint apparatus in micro- and small-scale work. With a nominal volume of 50 ml (0,05 l) and a net weight of 0,050 kg, it is well suited to teaching experiments, method development and limited-quantity synthesis. Manufactured to DIN/ISO 4797 and USP requirements and supplied as a single piece from manufacturer Labbox in the GLASSCO range, the flask offers the thermal and chemical resistance expected of borosilicate 3.3 laboratory glassware. The spherical shape supports uniform heating and efficient mixing under reflux or mild vacuum. Clear walls permit direct observation of reaction progress, boiling behaviour and phase separations. Typical applications include organic micro-reactions, solvent recovery, distillation receiving and general laboratory heating or cooling where a reliable NS 14/23 round-bottom flask is needed.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

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