Description
Ground two-neck pear-shaped flask, NS 14/23, is a 100 ml multi-neck vessel made from borosilicate glass LBG 3.3 for laboratory synthesis, distillation, and sample concentration. The pear-shaped design concentrates residual liquid at the base while the two ground joints allow simultaneous connection of condensers, addition funnels, or inert-gas lines. Nominal volume is 0,1 l (100 ml), with a net weight of 0,790 kg. Borosilicate glass 3.3 offers the thermal shock resistance and chemical durability required for everyday organic and preparative work. Available from manufacturer Labbox as a single piece, the flask mates with standard NS 14/23 ground-joint accessories and is well suited to heating-mantle or oil-bath setups. Its intermediate capacity bridges small-scale screening and larger preparative runs, giving laboratories a robust two-neck option without unnecessary complexity.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, pear shape, with two necks, 14/23, 100 ml
What is this article?
Flask, pear shape, with two necks, 14/23, 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.
