Flat-bottom flask with standard ground joint, LBG 3.3, NS 19/26, 250 ml is a borosilicate laboratory flask intended for everyday chemistry, sample preparation and small-scale reactions. Fabricated from borosilicate glass 3.3, it provides the chemical resistance and thermal performance associated with this material for heating, stirring and temporary holding of liquids. The flat bottom ensures secure placement on laboratory surfaces and hotplates, and the NS 19/26 standard ground joint supports connection to matching condensers, stoppers and adapters. Nominal capacity is 250 ml (0,25 l). The pack contains 10 pieces, making it convenient for shared laboratories, teaching courses and parallel experimental work. These flasks from manufacturer Labbox under the LBG line are suited to setups where a compact NS 19/26 joint and a stable flat base are required. Pack net weight is 1,350 kg. Pair with compatible NS 19/26 ground-joint components for consistent assemblies in distillation, reflux or general preparative procedures.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 250 ml, 10 stuks
What is this article?
Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 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.
