Description
Rotilabo® round bottom flask, narrow neck, is a 250 ml borosilicate glass laboratory vessel designed for routine chemical preparation, heating and mixing tasks. The flask has a classic round bottom and a narrow neck with a diameter of 34 mm, giving a practical balance between working volume, controlled access and compatibility with common stoppers and laboratory adapters. Round-bottom geometry promotes even heat distribution in heating mantles, water baths or oil baths, supporting dissolution, reaction mixtures and general preparative workflows. Borosilicate glass delivers the thermal and chemical resistance expected of standard laboratory glassware for research, teaching and quality-control environments. Supplied in a pack of 10 pieces from manufacturer ROTH SELECTION, the unit pack weighs 0,850 kg and is straightforward to stock and distribute within laboratory stores. This Rotilabo® narrow-neck round bottom flask forms part of the laboratory glass, vessels and consumables range and is intended for laboratories requiring reliable intermediate-volume round flasks for day-to-day experimental and sample-handling procedures.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Rotilabo®-round bot. flask, narrow neck, 250ml, borosiilicate glass
What is this article?
Rotilabo®-round bot. flask, narrow neck, 250ml, borosiilicate glass 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.
