Description
Round-bottom flask 50 ml NS 14/23 Economy is a clear laboratory flask intended for distillation, reaction and collection work. It is manufactured from borosilicate glass 3.3, offering the chemical resistance and thermal stability expected in routine organic and analytical laboratories. The vessel carries a standard ground joint NS 14/23 and a nominal capacity of 50 ml. External diameter is 51 mm and overall height is 90 mm, giving a compact profile that fits common heating mantles and clamps. Supplied as a single piece from manufacturer Witeg, this Economy series flask is suited to solvent recovery, sample preparation and small-scale synthesis where a reliable centre-neck round-bottom vessel is required. Clear glass walls permit continuous visual monitoring of contents and reaction progress. Typical application areas include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. Net weight is only 0,032 kg, so the item remains light yet robust enough for repeated heating and cooling cycles. The combination of standardised joint geometry, defined dimensions and borosilicate 3.3 construction supports interchangeable use with existing NS 14/23 glassware assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 50 ml ST 14/23 Economy
What is this article?
Round bottom flask 50 ml ST 14/23 Economy is the article on this page. Luminix Health distributes Witeg 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.
