Description
Erlenmeyer flask 250 ml NS 24/29 Economy is a graduated conical laboratory flask with standard ground joint NS 24/29 for routine mixing, sample preparation and reaction work. Made from clear borosilicate glass 3.3, it combines chemical durability with good thermal shock resistance for everyday bench use. Outer diameter is 85 mm and overall height 140 mm, giving a stable footprint and a practical 250 ml working volume. Graduation marks allow approximate volume checks during media make-up or dilution. The NS 24/29 joint accepts matching stoppers, condensers or adapters so the flask can be closed for storage, gentle reflux or transfer steps. Pack size is 10 pieces; each flask has a net weight of 0,109 kg and remains easy to handle on hotplates, water baths or orbital shakers. This Economy version from manufacturer Witeg is well suited to teaching laboratories, quality-control benches and general research environments that need reliable borosilicate glassware without specialised coatings. Clear walls permit continuous visual monitoring of colour changes, turbidity or precipitate formation. Compatible with aqueous solutions and many organic solvents that are suitable for borosilicate glass 3.3, the flask supports a wide range of standard laboratory workflows.

Questions about Erlenmeyer flask 250 ml ST 24/29 Economy
What is this article?
Erlenmeyer flask 250 ml ST 24/29 Economy 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.
