Description
Rotilabo® flat bottom flask with standard ground joint is a laboratory glass vessel for heating, reaction work, distillation setups, and general sample handling where a free-standing base is required. This 1000 ml flask is fitted with an NS45/40 ground joint, enabling secure, interchangeable connection to condensers, adapters, stoppers, and other jointed glassware commonly used in organic and analytical laboratories. The flat bottom allows the vessel to stand stably on the bench or hotplate surface without a cork ring or additional support, which is practical for routine workflows and teaching environments. Supplied as 1 pc and weighing 0,280 kg, the flask forms part of the Rotilabo® labware line from manufacturer ROTH SELECTION and is intended for chemistry, life-science, and educational laboratories that standardise on NS45/40 joints. Flat-bottom flasks with ground glass joints are frequently chosen for synthesis, solvent handling, and intermediate storage when both joint compatibility and bench stability matter. Clear glass construction supports visual monitoring of contents, colour changes, and phase behaviour during processes. Suitable for laboratories seeking a reliable 1000 ml jointed flat-bottom vessel for everyday experimental work.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Rotilabo®flat bottom flask, w. stand. ground joint, 1000 ml, NS45/40, 1 unit(s)
What is this article?
Rotilabo®flat bottom flask, w. stand. ground joint, 1000 ml, NS45/40, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
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.
