Description
Erlenmeyer flask 250 ml narrow neck with rim Boro 3.3 is a graduated conical flask for general laboratory mixing, preparation and culture applications. The nominal volume is 0,25 l. It is manufactured from borosilicate glass 3.3 and combines a narrow neck with rim, neck outer diameter 34 mm, flask outer diameter 85 mm and height 140 mm for stable handling and efficient swirling of contents. Graduation on the body supports approximate volume reading during routine media preparation, dilutions and sample work-up. Borosilicate glass 3.3 is a standard choice for laboratory glassware that must tolerate typical thermal and chemical conditions of bench-scale work. This version from manufacturer Witeg is packed as 10 pc(s), which is practical for laboratories that maintain multiple identical 250 ml narrow-neck Erlenmeyers across teaching, QC and research stations. Dimensional and material details follow the manufacturer description so purchasing and replacement remain straightforward within established glassware inventories.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flask 250 ml narrow neck with rim
What is this article?
Erlenmeyer flask 250 ml narrow neck with rim is the article on this page. Luminix Health distributes Witeg 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.
