Beschrijving
Round-bottom flask with standard ground joint NS 14/23 is a compact laboratory vessel in borosilicate glass LBG 3.3 with a nominal volume of 5 ml. The spherical body supports even heating and mixing of small sample volumes, while the standardised NS 14/23 joint allows secure connection to condensers, adapters, and other ground-joint glassware. Manufactured from borosilicate glass 3.3, the flask suits routine organic synthesis, distillation setups, and receiving or collection duties where thermal and chemical resistance are required. This pack contains 12 pieces, giving laboratories a convenient multi-unit supply for parallel reactions, teaching benches, or spare stock. With a net weight of 0,192 kg for the pack, the items remain easy to handle and store. Categories such as round-bottom flasks, ground-joint flasks, distillation flasks, and receiving flasks reflect typical use in preparative and analytical workflows. The LBG 3.3 glassware line from manufacturer Labbox provides a practical choice for small-scale chemistry, sample preparation, and general laboratory operations that rely on interchangeable standard joints and durable borosilicate construction.
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, 5 ml, 12 stuks
What is this article?
Kookkolf ronde bodem, LBG 3.3, mond 14/23, 5 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.
