Description
Pear-shaped flask with standard ground joint NS 14/23, 100 ml is a versatile laboratory flask for reaction mixtures, concentration and preparative chemistry at the 100 ml scale. Constructed from borosilicate glass 3.3 (LBG 3.3), it offers the chemical and thermal resistance associated with quality laboratory borosilicate. The pear-shaped design concentrates liquid toward the base, which supports efficient rotary evaporation, distillations and work with moderate sample volumes. A standard ground joint 14/23 ensures reliable coupling to condensers, adapters, receivers and other jointed apparatus used across European laboratories. Nominal volume is 100 ml (0,1 l) and net weight is 0,076 kg, giving a practical balance of capacity and handling. Available as a single unit from manufacturer Labbox, this flask is appropriate for research groups, teaching labs and quality-control environments that standardise on LBG borosilicate glassware. It accommodates organic synthesis steps, solvent recovery and general sample preparation while remaining fully compatible with common NS 14/23 ground-joint systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, pear shape, 14/23, LBG 3.3, 100 ml
What is this article?
Flask, pear shape, 14/23, LBG 3.3, 100 ml is the article on this page. Luminix Health distributes Labbox 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.
