Description
DURAN® flat-bottom flask with wide neck and beaded rim is a versatile laboratory vessel of borosilicate glass 3.3 offering a nominal volume of 1 l. Bulbous flasks of this type serve as universal labware alongside beakers and are routinely employed for distillations or for heating liquids. The flat base permits stable standing without a support ring, while the wide neck simplifies filling and cleaning. A permanently fired white enamel marking remains durable under repeated use. Flat-bottom and round-bottom versions, narrow- or wide-neck styles, and models with or without ground joints are available so that the appropriate vessel can be chosen for each application. Produced by Duran/DWK Life Sciences, this 1000 ml flask is intended for heating duties and everyday laboratory procedures. Its robust borosilicate glass 3.3 construction provides the thermal and chemical resistance expected in routine experimental work, making it a practical choice for general chemistry and preparation tasks requiring larger working volumes.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about DURAN® Flat Bottom Flask, wide neck, with beaded rim
What is this article?
DURAN® Flat Bottom Flask, wide neck, with beaded rim is the article on this page. Luminix Health distributes DWK Life Sciences 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.
