Beschrijving
Round-bottom flask with standard ground joint NS 29/32 is a borosilicate glass LBG 3.3 vessel with a nominal volume of 100 ml, supplied in a multipack for laboratory use. The spherical form promotes uniform heating and mixing during reaction, distillation and collection steps, while the NS 29/32 ground joint ensures compatibility with common condensers, still heads and adapters in jointed glass assemblies. Produced from borosilicate glass 3.3 by manufacturer Labbox within the LBG product type, the flask is intended for routine organic synthesis, preparative work-up and teaching laboratories that standardise on NS 29/32 connections. The pack contains 12 pieces, which is practical for parallel experiments, multi-user benches or maintaining spare stock. Relevant application categories include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. Pack net weight is 0,995 kg. Combining a 100 ml working volume with a larger standard joint and durable LBG 3.3 glass, this multipack supports efficient laboratory organisation wherever interchangeable NS 29/32 round-bottom flasks are required for everyday chemical handling and glassware setups.
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, 100 ml, 12 stuks
What is this article?
Kookkolf met ronde bodem, LBG 3.3, mond 29/32, 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.
