Description
Round-bottom flask with standard ground joint GLASSCO NS 29/32, 500 ml is a laboratory flask designed for distillation, reflux, collection and general heating work under controlled conditions. Manufactured from high-quality borosilicate glass LBG 3.3, it offers the thermal shock resistance and chemical durability expected in routine and preparative chemistry. The vessel follows DIN/ISO 4797 and United States Pharmacopeia (USP) requirements, supporting reliable interchange with standard ground-joint apparatus. A nominal volume of 0,5 l and an NS 29/32 joint provide a practical working capacity for medium-scale reactions, solvent recovery and receiving duties. The spherical body promotes even heat distribution when used with heating mantles or oil baths, while the ground joint ensures a tight, greaseable connection to condensers, adapters and other glassware. Supplied as a single piece from manufacturer Labbox under the GLASSCO line, the flask has a net weight of 0,400 kg and suits teaching laboratories, research benches and process development where robust borosilicate round-bottom flasks with standardised joints are required. Categories of use include round-bottom, ground-joint, distillation and receiving flask applications.
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, 500 ml
What is this article?
Boiling flask round bottom, GLASSCO, mouth 29/32, 500 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.
