Flat-bottom flask with standard ground joint, LBG 3.3, NS 29/32, 250 ml is a laboratory vessel for general chemistry, preparative work and routine sample handling. Made from borosilicate glass 3.3, it combines the thermal-shock resistance and chemical durability expected of this glass type for heating, mixing and short-term storage of reagents and reaction mixtures. The flat base gives stable standing on the bench or hotplate, while the NS 29/32 standard ground joint allows reliable connection to condensers, adapters, drying tubes and other jointed apparatus in distillation or reflux setups. Nominal volume is 250 ml (0,25 l). Supplied in a pack of 10 pieces, the set is practical for teaching laboratories, quality-control benches and multi-user research environments. These flasks from manufacturer Labbox (LBG product type) suit applications where a stable, jointed flat-bottom vessel is preferred over round-bottom designs. Pack net weight is 1,327 kg. Use with compatible NS 29/32 glassware for secure, leak-resistant assemblies in everyday laboratory workflows.
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 29/32, 250 ml, 10 stuks
What is this article?
Kookkolf, vlakke bodem, LBG 3.3, hals 29/32, 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.
