Description
Rotilabo® flat bottom flask, 250 ml is a mid-volume laboratory flask intended for solution preparation, reagent holding, and general wet-chemistry tasks that benefit from a stable flat base. The vessel features a narrow neck and a heavy duty rim, promoting controlled pouring, reduced splash, and secure placement of stoppers during routine operations. Standing height is 140 mm, matching typical bench-scale 250 ml workflows in teaching, analytical, and research laboratories. Packaged as 10 pc(s) with a weight of 1,050 kg, the unit supports efficient restocking of shared glassware stores. This Rotilabo® flask from manufacturer ROTH SELECTION fits everyday laboratory practice where durable flat-bottom vessels are preferred for upright storage and use on hot plates with suitable supports. The narrow-neck geometry helps limit evaporative loss relative to wide-mouth containers, while the reinforced rim strengthens the opening against mechanical stress from repeated handling and closure cycles. Defined capacity and height simplify rack assignment, shelf planning, and inventory control across multi-user facilities. Suitable for aqueous and organic media within standard laboratory glassware procedures, the 250 ml format bridges smaller analytical aliquots and larger preparative batches without introducing specialised joint systems.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Rotilabo®-flat bottom flask, 250 ml, narrow neck, heavy duty rim, H 140 mm
What is this article?
Rotilabo®-flat bottom flask, 250 ml, narrow neck, heavy duty rim, H 140 mm 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.
