Description
DURAN® filter flasks with KECK™ mounting set in Erlenmeyer shape function as collecting vessels for the filtrate in vacuum filtration setups. Their thick wall construction makes the 100 ml capacity flasks vacuum-resistant and suitable for reduced-pressure work. Vacuum is applied through a side arm that accepts a glass or replaceable plastic olive, while the large neck opening holds a rubber adapter together with a filter funnel. Produced from borosilicate glass 3.3 by manufacturer Duran/DWK Life Sciences, these DURAN® flasks comply with the provisions of the Equipment and Product Safety Act and feature a permanently fired white enamel marking for long-term legibility. Smaller volumes of 2000 ml and below are supplied in the classic Erlenmeyer geometry. Advantages include robust vacuum performance, interchangeable plastic olives and durable printed markings. They are intended for aspirating liquids, filtration at reduced pressure and general safe vacuum filtration procedures in analytical and preparative laboratories.
This article belongs on Erlenmeyer flasks, in Beakers & flasks.

Questions about DURAN® Filtering Flask, with KECK™ Assembly set, Erlenmeyer shape
What is this article?
DURAN® Filtering Flask, with KECK™ Assembly set, 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.
