Description
Round-bottom flask, 1000 ml, socket NS 29/32 is a single-neck laboratory vessel constructed from borosilicate glass 3.3. It incorporates a medium neck finished with a ground joint of NS 29/32 for leak-free coupling to condensers, adapters and other modular glassware. The spherical shape supports uniform heat transfer and is well suited to larger-scale distillations, reflux reactions and collection of distillates. Nominal volume reaches 1000 ml with a net weight of 0,279 kg, offering substantial capacity while remaining practical for bench-top use. From manufacturer Rettberg, the flask provides the proven chemical inertness and thermal-shock resistance of borosilicate glass 3.3 required in synthetic, preparative and analytical laboratories. The medium-neck configuration facilitates stirring, reagent addition and temperature monitoring without excessive bulk. Supplied as one piece, it integrates immediately into standard ground-joint assemblies for distillation trains, rotary evaporators and general reaction setups.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask, 1000 ml, socket size 29/32
What is this article?
Round bottom flask, 1000 ml, socket size 29/32 is the article on this page. Luminix Health distributes Rettberg 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.
