Description
Round-bottom flask 250 ml NS 24/29 Economy is a clear laboratory flask intended for distillation, reaction and collection work. Made from borosilicate glass 3.3, it combines chemical durability with the thermal resistance required for everyday heating and cooling cycles. The vessel carries a standard ground joint NS 24/29, ensuring reliable connection to condensers, adapters and complementary glassware. Outer diameter is 85 mm and overall height is 140 mm, giving a compact 250 ml working volume suited to preparative and analytical routines. Packaged as 10 pc(s) and available from manufacturer Witeg, this Economy series flask supports general distillation setups, receiving applications and ground-joint apparatus assemblies. Clear glass walls permit straightforward visual monitoring of contents during reflux, solvent recovery or sample concentration. The borosilicate 3.3 construction remains compatible with common organic solvents and aqueous media, making the flask a practical choice for routine laboratory glassware inventories.

Questions about Round bottom flask 250 ml ST 24/29 Economy
What is this article?
Round bottom flask 250 ml ST 24/29 Economy is the article on this page. Luminix Health distributes Witeg 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.
