Beschrijving
Flat-bottom flask with standard ground joint LBG 3.3, NS 24/29, 250 ml is a laboratory standing flask designed for routine heating, mixing, and reaction work on a stable base. Manufactured from borosilicate glass 3.3 (LBG 3.3), it combines thermal shock resistance with chemical durability suited to aqueous and many organic media. The nominal volume is 0,25 l, giving a practical working capacity for medium-scale preparations, distillations under mild conditions, and storage of intermediate solutions. A precision NS 24/29 standard ground joint supports secure connection to condensers, adapters, stoppers, and other jointed glassware without additional sealing media in many setups. The flat base allows the vessel to stand freely on the bench or on a hotplate, improving handling safety compared with round-bottom designs when magnetic stirring or gentle heating is required. Net weight is approximately 0,106 kg. This flat-bottom flask from manufacturer Labbox belongs to the LBG product line and is supplied as a single piece for analytical, synthetic, and teaching laboratories that standardise on borosilicate 3.3 glassware and NS joint systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask, flat bottom, LBG 3.3, mouth 24/29, 250 ml
What is this article?
Boiling flask, flat bottom, LBG 3.3, mouth 24/29, 250 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, 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.
