Description
Round-bottom flask with standard ground joint NS 14/23, LBG 3.3, is a compact laboratory flask for heating, distillation, reaction and receiving applications. Fabricated from borosilicate glass 3.3 (LBG 3.3), it combines chemical resistance with the thermal performance expected of this glass type in routine laboratory work. Nominal volume is 25 ml (0,025 l), a practical size for small-scale synthesis, sample concentration and intermediate collection steps. The NS 14/23 standard ground joint ensures reliable, interchangeable coupling to condensers, dropping funnels, adapters and other jointed glassware. This single-piece unit from manufacturer Labbox is convenient for dedicated setups, method development and individual workstation stocking. Net weight is 0,023 kg. The round bottom supports uniform heating in mantles or oil baths, and the transparent LBG 3.3 wall permits clear observation of boiling, mixing or phase behaviour. It fits categories such as round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks across research, quality-control and teaching laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 14/23, 25 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 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.
