Description
Pointed flask 250 ml NS 14/23 Economy is a clear laboratory flask manufactured from borosilicate glass 3.3 for everyday chemical and analytical applications. It offers a nominal volume of 250 ml together with a standard ground joint NS 14/23 and a pointed bottom that facilitates concentration work and thorough drainage of residual liquid. Outer diameter is 85 mm and height is 145 mm, resulting in a compact vessel that fits readily on the bench or in heating equipment. Clear borosilicate glass 3.3 from manufacturer Witeg delivers reliable chemical resistance and thermal performance for heating, cooling and solvent operations. Supplied in packs of 10 pieces, this Economy pointed flask is well suited to routine preparative chemistry, sample preparation and general laboratory use where visual monitoring of the contents is required. The standardised NS joint ensures straightforward connection to matching glassware and stoppers, while the pointed geometry supports efficient recovery of small sample volumes after evaporation or crystallisation.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 250 ml ST 14/23 Economy
What is this article?
Flask pear shaped 250 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.
