Description
Flat-bottom flask with standard ground joint NS 14/23 is a 25 ml laboratory vessel made from borosilicate glass 3.3 (LBG 3.3). The nominal volume of 0,025 l suits small-scale reactions, sample preparation, heating on a hot plate, and general wet-chemistry work where a stable standing base is required. The NS 14/23 ground joint provides a standardised connection for condensers, adapters, stoppers, and other jointed glassware, supporting secure assembly in distillation, reflux, or extraction setups. Manufactured from borosilicate glass 3.3, the flask offers the thermal and chemical resistance typical of this material class for routine laboratory use. This single-piece unit from manufacturer Labbox has a net weight of 0,030 kg and is intended for everyday bench applications in research, teaching, and quality-control laboratories. The flat bottom allows direct placement on heating surfaces or magnetic stirrers when used with appropriate support. Clear joint sizing and the LBG 3.3 designation help laboratories match the flask to existing ground-joint systems and glassware inventories without ambiguity.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

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