Description
Round-bottom flask with standard ground joint GLASSCO NS 29/32, 5000 ml is a large-capacity laboratory flask for scale-up distillation, bulk reflux, solvent recovery and receiving applications. Fabricated from high-quality borosilicate glass LBG 3.3, it combines chemical resistance with the thermal performance needed for larger heated volumes. Compliance with DIN/ISO 4797 and United States Pharmacopeia (USP) supports interchangeability with standard NS jointware across preparative and process-support setups. The nominal volume of 5 l and NS 29/32 ground joint give a substantial working capacity while retaining a common joint size for condensers, adapters and transfer lines. The spherical profile aids heat distribution when the flask is used with appropriately sized heating mantles or baths. Supplied as one piece from manufacturer Labbox in the GLASSCO range, the unit has a net weight of 1,870 kg and is suited to research pilot work, teaching demonstrations at larger scale and laboratory production steps that require a robust 5000 ml round-bottom flask. Relevant use categories include round-bottom, ground-joint, distillation and collection flasks.
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, 5000 ml, 1 pcs
What is this article?
Boiling flask round bottom, GLASSCO, mouth 29/32, 5000 ml, 1 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.
