Description
DURAN® filter flask with glass olive, Erlenmeyer shape, 250 ml functions as a robust collection vessel for filtrate during vacuum filtration. Made of borosilicate glass 3.3 with thick walls, it withstands vacuum applications reliably. Vacuum is applied via the side glass olive; the wide neck accepts a rubber sleeve and filter funnel. Erlenmeyer geometry is standard for volumes of 2000 ml and below. Permanent white enamel markings ensure long-term legibility. Nominal volume is 0,25 l with a net weight of 0,29 kg. Offered by manufacturer Duran/DWK Life Sciences, the flask streamlines preparative and analytical laboratory filtration, lowers accident risk under vacuum, and enables safe liquid aspiration at reduced pressure. It is well suited to everyday filtration, vacuum filtration and related reduced-pressure techniques in research and industrial laboratories.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about DURAN® Filtering Flask, with glass hose connection, Erlenmeyer shape
What is this article?
DURAN® Filtering Flask, with glass hose connection, Erlenmeyer shape is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
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.
