Beschrijving
Round-bottom flask with standard ground joint NS 14/23, LBG 3.3, is laboratory glassware intended for heating, distillation, reaction and receiving work at small scale. It is made from borosilicate glass 3.3 (LBG 3.3), a material chosen for thermal shock resistance and chemical durability in everyday lab practice. The nominal volume is 10 ml (0,01 l), suited to micro-preparations, sample handling and compact distillation or collection setups. The NS 14/23 ground joint provides a standardised, interchangeable connection to condensers, adapters, stoppers and other jointed apparatus. Offered as a pack of 12 pieces from manufacturer Labbox, the set supports parallel experiments, teaching classes and routine stock replenishment. Pack net weight is 0,192 kg. The spherical body promotes even heat distribution when used with heating mantles or baths, while the clear glass allows continuous visual monitoring of contents. Typical placements include round-bottom, ground-joint, distillation and receiving flask roles on synthetic chemistry benches and student laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf ronde bodem, LBG 3.3, mond 14/23, 10 ml, 12 stuks
What is this article?
Kookkolf ronde bodem, LBG 3.3, mond 14/23, 10 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.
