Description
Flat-bottom flask with standard ground joint, LBG 3.3, NS 24/29, 250 ml is a laboratory glassware item for general synthetic work, heating and reagent handling. Produced from borosilicate glass 3.3, it offers the thermal and chemical resistance typical of this glass grade for routine bench and hotplate use. The flat base provides stable standing without a cork ring, while the NS 24/29 standard ground joint enables secure coupling to condensers, adapters and other jointed apparatus. Nominal volume is 250 ml (0,25 l). Delivered as a pack of 10 pieces, the product supports multi-station laboratories, training environments and workflows that need several identical vessels. These flasks from manufacturer Labbox (LBG type) are appropriate where an NS 24/29 joint and a flat-bottom geometry are preferred for distillation, reflux or intermediate storage. Pack net weight is 1,350 kg. Combine with matching NS 24/29 components to build reliable, interchangeable glass assemblies for everyday laboratory practice.
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, 10 pcs
What is this article?
Boiling flask, flat bottom, LBG 3.3, mouth 24/29, 250 ml, 10 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
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.
