Description
Narrow neck Erlenmeyer flasks, DURAN®, are graduated laboratory vessels with a 250 ml capacity intended for routine laboratory handling. Each unit features a conical body, narrow neck and graduation marks that support approximate volume assessment during solution preparation and sample work. The flasks are specified to ISO 1773 and are offered as a pack of 10 pc(s), providing a ready multi-unit supply for general glassware stocks. They come from manufacturer DWK Life Sciences as part of the DURAN® range of laboratory glass vessels used with beakers and other Erlenmeyer formats. With a pack weight of 1,360 kg, the ten-piece set remains practical to store, transport and issue across teaching, analytical and research benches. The narrow-neck conical shape suits mixing, dilution and temporary holding of liquids wherever graduated 250 ml flasks are called for. Laboratories specifying ISO 1773 narrow-neck Erlenmeyer flasks receive a consistent pack focused on the stated capacity, graduation and standard, without further performance claims beyond the manufacturer data.

Questions about Narrow neck Erlenmeyer flasks, DURAN®, graduation, 250 ml, ISO 1773, 10 unit(s)
What is this article?
Narrow neck Erlenmeyer flasks, DURAN®, graduation, 250 ml, ISO 1773, 10 unit(s) 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.
