Description
DURAN® filter flask with glass olive in bottle shape is a thick-walled laboratory vessel intended as the filtrate collection container during vacuum filtration. Made from borosilicate glass 3.3, the flask withstands vacuum applications thanks to its massive wall thickness and supports safe working under reduced pressure. Vacuum is applied via the lateral glass-olive side connection, while the large neck opening accepts a rubber sleeve together with a Büchner funnel or filter nutsche. Flasks above 2000 ml are supplied in bottle form rather than Erlenmeyer shape; this 5 l nominal-volume model follows that bottle geometry. The design with side tubulature simplifies preparative and analytical laboratory work and simultaneously lowers accident risk. An enamelled white print marking is fired into the glass for permanent, durable identification. Typical uses include aspiration of liquids, filtration at reduced pressure and general vacuum filtration. This robust glassware from manufacturer Duran/DWK Life Sciences is supplied as a single piece and is well suited to routine and preparative filtration tasks in research and quality-control laboratories.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about DURAN® Filtering Flask, with glass hose connection, bottle shape
What is this article?
DURAN® Filtering Flask, with glass hose connection, bottle 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.
