Description
Round-bottom flask 5 ml NS 14/23 Economy is a single-neck laboratory flask intended for distillation, reaction and small-volume collection tasks. It combines a nominal volume of 5 ml with a standard ground joint NS 14/23 for direct compatibility with common European glassware systems. The clear body is made from borosilicate glass 3.3, providing the thermal stability and chemical resistance expected in routine analytical and preparative work. Outer diameter measures 33 mm and overall height is 64 mm, yielding a compact profile for bench, mantle or block use. A medium-neck configuration supports secure attachment of stoppers, condensers or adapters. Supplied in packs of 10 pieces from manufacturer Witeg, the Economy flask suits teaching labs, micro-scale synthesis and sample preparation where dependable round-bottom geometry is needed. Applications include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks that demand consistent joint fit and everyday chemical durability.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 5 ml ST 14/23 Economy
What is this article?
Round bottom flask 5 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 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.
