Description
Round-bottom flask with standard ground joint LBG 3.3, NS 19/26, is a laboratory vessel made from borosilicate glass 3.3 for distillation, reaction and receiving work. It offers a nominal volume of 500 ml (0,5 l) and a standard ground joint NS 19/26, so it couples cleanly with matching condensers, adapters and other ground-joint apparatus in organic synthesis and preparative setups. The spherical body supports even heating and mixing when used with heating mantles or baths. This pack of 6 pieces from manufacturer Labbox suits multi-station laboratories and teaching environments that need interchangeable glassware. Typical applications fall under round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. LBG 3.3 borosilicate glass provides the thermal and chemical resistance expected of laboratory borosilicate ware. Pack net weight is 1,170 kg. The standardized NS joint helps achieve reliable, leak-tight connections in routine laboratory assemblies without proprietary fittings.
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 19/26, 500 ml, 6 pcs
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 19/26, 500 ml, 6 pcs 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.
