Description
Pointed flask 25 ml NS 14/23 Economy is a cost-efficient laboratory vessel with a tapered base designed for small-scale reactions and complete liquid recovery. It is produced from clear borosilicate glass 3.3, providing the chemical durability and thermal performance expected in everyday laboratory practice. A single neck with standard ground joint NS 14/23 ensures compatibility with common condensers, stoppers and adapters. Dimensions include an outer diameter of 43 mm and a height of 90 mm, corresponding to a nominal volume of 25 ml. This Economy pointed flask from manufacturer Witeg is intended for distillation, concentration steps, extraction work and analytical sample handling where residual volume must be minimised. The pointed tip promotes thorough drainage and supports accurate work with limited sample amounts. Packs contain 10 pieces, with a net weight of 0,026 kg per flask. Clear borosilicate glass 3.3 construction suits organic synthesis, pharmaceutical laboratory tasks and general wet-chemistry applications in teaching, research and quality-control environments that require reliable jointed glassware at an economical specification level.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 25 ml ST 14/23 Economy
What is this article?
Flask pear shaped 25 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.
