Description
Pear-shaped flask with standard ground joint NS 14/23, 25 ml is a compact laboratory vessel for small-volume chemical work, sample concentration and reaction setups. Made from borosilicate glass 3.3 (LBG 3.3), the flask combines thermal stability with chemical resistance suited to routine organic and analytical procedures. The pear-shaped body gathers liquid at the base, which is practical for rotary evaporation, distillations and handling limited sample quantities. A standard ground joint 14/23 allows secure connection to condensers, adapters, drying tubes and other jointed glassware without improvised fittings. Nominal volume is 25 ml (0,025 l) and net weight is 0,034 kg, so the piece remains easy to handle on the bench or in a heating bath. Supplied as a single unit from manufacturer Labbox, this flask fits teaching laboratories, research benches and quality-control workflows where reliable LBG borosilicate glassware and standardised joint geometry are required. It supports everyday synthesis steps, solvent recovery and preparatory chemistry while remaining compatible with common European 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, 25 ml
What is this article?
Flask, pear shape, 14/23, LBG 3.3, 25 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.
