Round-bottom flask with standard ground joint GLASSCO, NS 29/32, 3000 ml is a high-volume laboratory flask manufactured from high-quality borosilicate glass 3.3 (LBG 3.3). It provides a nominal volume of 3 l together with an NS 29/32 ground joint for secure coupling to condensers, adapters and other standard jointware. The spherical design aids uniform heat transfer and is intended for distillation, larger-scale reactions and use as a receiving or collection flask. Produced according to DIN/ISO 4797 and the American Pharmacopoeia (USP), this GLASSCO item is available as a single piece from manufacturer Labbox and has a net weight of 1,110 kg. Borosilicate glass 3.3 offers the chemical and thermal resistance required for demanding preparative work in research and teaching laboratories. Application areas cover round-bottom, ground-joint, distillation and collection flask tasks where a durable 3-litre vessel with a standardised NS 29/32 joint is needed for reliable assembly of multi-component glass apparatus.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf met ronde bodem, GLASSCO, hals 29/32, 3000 ml, 1 stuk
What is this article?
Kookkolf met ronde bodem, GLASSCO, hals 29/32, 3000 ml, 1 stuk is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
