Description
Rotilabo® round bottom flask, 500 ml is a laboratory glass vessel made from borosilicate glass with a standard ground joint NS 45/40. It is intended for chemical synthesis, distillation, reflux and heating work where a spherical reaction space supports even heat distribution and efficient mixing. The 500 ml working volume suits medium-scale preparations, intermediate reaction steps and teaching demonstrations. Clear borosilicate walls allow visual monitoring of colour changes, boiling behaviour and phase separations during experiments. The NS 45/40 joint connects readily to common condensers, adapters, stoppers and other ground-glass components used in organic and inorganic setups. Supplied as one piece with a weight of 0,240 kg, the flask is practical for routine bench work when held in a heating mantle, cork ring or clamp assembly. This Rotilabo® flask from manufacturer ROTH SELECTION integrates into standard laboratory glassware trains for research, quality control and educational laboratories. Its round-bottom geometry remains a core format for controlled heating under atmospheric or reduced pressure when paired with appropriate supports and safety equipment.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Rotilabo®-round bottom flask, 500 ml, borosilicate glass, NS 45/40, 1 unit(s)
What is this article?
Rotilabo®-round bottom flask, 500 ml, borosilicate glass, NS 45/40, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
