Beschrijving
Round-bottom flask with standard ground joint NS 29/32 is a 1000 ml laboratory flask fabricated from borosilicate glass LBG 3.3 for medium- to larger-scale heating, distillation and collection tasks. The round bottom distributes heat uniformly and supports magnetic or mechanical stirring, while the NS 29/32 ground joint provides a secure, standardised interface to condensers, dropping funnels and vacuum adapters. Made from borosilicate glass 3.3 by manufacturer Labbox, the vessel combines good chemical resistance with the thermal stability needed for reflux, solvent evaporation and preparative work. Nominal volume is 1 l, making the flask suitable for batch reactions, distillate receivers and temporary storage of process liquids. The pack contains 6 pieces, convenient for multi-setup laboratories and teaching courses. Pack net weight is 2,032 kg. These flasks are commonly used as reaction vessels, distillation flasks and collection flasks in organic synthesis, analytical sample preparation and general laboratory practice where interchangeable ground-joint glassware is essential.

Questions about Kookkolf met ronde bodem, LBG 3.3, mond 29/32, 1000 ml, 6 stuks
What is this article?
Kookkolf met ronde bodem, LBG 3.3, mond 29/32, 1000 ml, 6 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.
