Description
Round-bottom flask with standard ground joint NS 29/32 is a larger-capacity laboratory vessel for distillation, reaction scale-up and collection work. It is manufactured from high-quality borosilicate glass LBG 3.3, providing thermal and chemical resistance suitable for demanding laboratory heating and solvent handling. Nominal volume is 2000 ml (2 l), and the spherical body aids even heat transfer when used with appropriately sized heating mantles or baths. The NS 29/32 joint allows secure, interchangeable coupling to condensers, adapters and other standard ground-joint apparatus. Construction follows DIN/ISO 4797 and the American Pharmacopeia (USP), supporting consistent quality expectations for jointed borosilicate glassware. Offered as a single piece under the GLASSCO product type from manufacturer Labbox, this flask fits research, preparative and teaching environments that require a two-litre round-bottom format. Typical roles include larger-scale organic reactions, solvent recovery and use as a distillation or receiving flask within NS 29/32 assemblies. Net weight is 0,495 kg. The borosilicate 3.3 material withstands common laboratory temperature variations and reagents encountered in synthesis and purification workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, GLASSCO, mouth 29/32, 2000 ml
What is this article?
Boiling flask round bottom, GLASSCO, mouth 29/32, 2000 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.
