Description
Erlenmeyer flask DURAN® 50 ml narrow neck with beaded rim is a conical laboratory flask in borosilicate glass 3.3, intended for everyday mixing, heating and media work. White graduation markings aid approximate volume reading during preparation and culture handling. The narrow-neck geometry with beaded rim is specified according to DIN 12 380, supporting secure stoppering and controlled pouring while reinforcing the mouth against mechanical stress. Key dimensions include a height of 85 mm, a neck diameter of 22 mm and a nominal volume of 50 ml (0,05 l). DURAN® borosilicate glass 3.3 offers the chemical durability and thermal shock resistance expected in analytical and life-science laboratories. These flasks from manufacturer Hirschmann are packed as 10 pc(s), making them practical for bench stock and shared instrument rooms. The conical body promotes efficient swirling and dissolution with reduced splash risk compared with cylindrical vessels. Suitable for chemistry, biology, microbiology and quality-control workflows that require graduated narrow-neck Erlenmeyer glassware compliant with established DIN practice.

Questions about ERLENMEYER FLASK DURAN 50 ML, NARROW NECK WITH RIM
What is this article?
ERLENMEYER FLASK DURAN 50 ML, NARROW NECK WITH RIM is the article on this page. Luminix Health distributes Hirschmann 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.
