Description
Ground two-neck pear-shaped flask, NS 14/23 with centre neck, is a 25 ml laboratory flask manufactured from borosilicate glass LBG 3.3. The pear-shaped body and dual ground joints support distillation, reaction, and concentration work where a compact vessel with two access points is required. Nominal volume is 0,025 l (25 ml), and the net weight is 0,040 kg. Borosilicate glass 3.3 provides the thermal and chemical resistance expected in routine organic and analytical chemistry. This flask from manufacturer Labbox is supplied as a single piece and fits standard NS 14/23 ground-joint assemblies, making it straightforward to integrate with condensers, dropping funnels, or stoppers. The centre-neck configuration keeps the second joint aligned for convenient setup on a stand or heating mantle. Suitable for teaching laboratories and research benches that need durable multi-neck glassware in a small working volume.
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, 25 ml
What is this article?
Flask, pear shape, with two necks, 14/23, 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.
