Description
Erlenmeyer flask with graduation, borosilicate glass 3.3, fitted with NS glass stopper and 25 ml nominal volume is a conical laboratory flask designed for mixing, heating and short-term storage. The flask is manufactured from borosilicate glass 3.3 and carries permanent graduation marks for approximate volume reading. It is closed by a matching NS glass stopper with joint size NS 14/23, ensuring a tight seal. Nominal volume is given as 0,025 l (25 ml). Supplied as a single piece from manufacturer Hecht, the flask belongs to the Erlenmeyer and culture-flask families used in chemistry, microbiology and general laboratory practice. The wide base and narrow neck of the Erlenmeyer shape promote efficient swirling while reducing splash risk. The combination of borosilicate glass 3.3, graduated scale and NS 14/23 glass stopper makes the item suitable for preparative work, titrations and sample handling where a stoppered conical vessel of 25 ml capacity is required. Each unit is ready for immediate use on the laboratory bench.

Questions about Erlenmeyer flasks, borosilicate glass 3.3, with interchangeable glass stopper
What is this article?
Erlenmeyer flasks, borosilicate glass 3.3, with interchangeable glass stopper is the article on this page. Luminix Health distributes Hecht 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.
