Beschrijving
Round-bottom flask with standard ground joint NS 24/29 is a 100 ml laboratory vessel made from borosilicate glass LBG 3.3 for routine synthesis, distillation and collection work. The spherical body promotes even heating and efficient mixing under reflux or reduced pressure, while the precision-ground NS 24/29 joint ensures a reliable, interchangeable connection to condensers, adapters and other ground-joint glassware. Manufactured from borosilicate glass 3.3 (Labbox), the flask offers the thermal shock resistance and chemical durability expected in organic, analytical and preparative laboratories. The nominal volume of 0,1 l suits small-scale reactions, solvent recovery and intermediate storage. Supplied as a pack of 12 pieces, the set supports parallel experiments, teaching practicals and continuous workflow without frequent reordering. Net weight of the pack is 0,776 kg. Typical applications include reaction vessels, distillation receivers and collection flasks in chemistry, life-science and quality-control environments where standardised ground joints and robust borosilicate construction are required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf met ronde bodem, LBG 3.3, mond 24/29, 100 ml, 12 stuks
What is this article?
Kookkolf met ronde bodem, LBG 3.3, mond 24/29, 100 ml, 12 stuks 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.
