Description
DURAN® flat-bottom flask with narrow neck and beaded rim is a versatile laboratory vessel of borosilicate glass 3.3 with a nominal volume of 10 l. Bulbous flasks of this type are used alongside beakers as universal containers for distillations, heating of liquids and related preparative work. The flat base allows the flask to stand freely without a support ring, while the narrow neck and beaded rim facilitate secure handling and simple closures or connections. A permanently fired white print provides durable, long-lasting labelling that remains legible under laboratory conditions. Supplied by manufacturer Duran/DWK Life Sciences, the flask belongs to the established DURAN® range of laboratory glassware. Flasks are offered in many configurations—narrow or wide neck, with or without ground joints, round-bottom or flat-bottom—so the appropriate geometry can be chosen for each application. Borosilicate glass 3.3 delivers the chemical resistance and thermal stability expected for routine heating and distillation tasks. This 10 l Enghals Stehkolben is intended for general laboratory use where a free-standing, large-volume vessel is required.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about DURAN® Flat Bottom Flask, narrow neck, with beaded rim
What is this article?
DURAN® Flat Bottom Flask, narrow 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.
