Round-bottom flask with standard ground joint NS 29/32 is a 250 ml borosilicate glass LBG 3.3 vessel designed for everyday laboratory heating, reflux and collection applications. The spherical shape supports even heat transfer and effective mixing, and the precision NS 29/32 joint connects reliably to standard condensers, adapters and other ground-joint components. Produced from borosilicate glass 3.3 (Labbox), the flask delivers the chemical resistance and thermal performance required in organic synthesis, sample work-up and preparative routines. Nominal volume of 0,25 l is well suited to intermediate-scale reactions, distillate collection and temporary holding of solutions. Supplied in a pack of 10 pieces, the set enables parallel runs, shared bench stocks and teaching laboratories. Net weight of the pack is 1,390 kg. Typical uses include reaction flasks, distillation receivers and collection vessels wherever standardised ground joints and durable borosilicate construction are specified for chemistry and related laboratory workflows.
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 29/32, 250 ml, 10 stuks
What is this article?
Kookkolf met ronde bodem, LBG 3.3, mond 29/32, 250 ml, 10 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.
