Description
Erlenmeyer flask 50 ml Boro 3.3 is a narrow-neck conical laboratory flask with ground joint NS 19/26, produced from borosilicate glass 3.3. White graduation markings aid volume orientation during preparation, mixing and routine handling. Nominal volume is 50 ml and height is 85 mm, making the flask suitable for dissolution work, gentle heating, media preparation and general sample processing in chemical and biological laboratories. The narrow neck with NS 19/26 joint supports secure coupling to compatible ground-joint stoppers and apparatus. Built to DIN ISO 4797, the glassware combines the chemical resistance and thermal performance expected from borosilicate glass 3.3. These Erlenmeyer flasks from manufacturer Hirschmann come in packs of 10 pieces and fit teaching labs, R&D benches and quality-control settings that rely on standardised conical flasks. The conical body encourages effective swirling of contents while reducing splash risk relative to cylindrical containers. An everyday laboratory flask for applications that call for a graduated narrow-neck Erlenmeyer with a defined NS 19/26 joint.

Questions about ERLENMEYER FLASK 50 ML, NARROW NECK WITH NS 19/26
What is this article?
ERLENMEYER FLASK 50 ML, NARROW NECK WITH NS 19/26 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.
