Description
Erlenmeyer flask 250 ml Boro 3.3 is a wide-neck conical laboratory flask with beaded rim, produced from borosilicate glass 3.3 and marked with clear white graduations. It offers a nominal volume of 250 ml (0,25 l), a height of 140 mm and a neck diameter of 50 mm, giving a practical balance of working volume and handling for mixing, dilution and sample preparation. The wide neck simplifies addition of solids and liquids as well as cleaning, while the beaded rim strengthens the opening for repeated laboratory use. Manufactured to DIN ISO 24450, the flask is appropriate for general chemical, biological and quality-control applications that benefit from the thermal and chemical durability of borosilicate 3.3 glass. Packs of 10 pieces from manufacturer Hirschmann provide a convenient supply for culture work, media preparation and routine bench procedures. Delivery is subject to remaining stock.

Questions about ERLENMEYER FLASK 250 ML, WIDE NECK WITH RIM
What is this article?
ERLENMEYER FLASK 250 ML, WIDE 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.
