Description
Erlenmeyer flask, wide neck, 250 ml, LBG 3.3 is a mid-volume conical laboratory flask manufactured from borosilicate glass 3.3 for chemistry, culture and general sample work. The wide neck with rim and graduation markings enables easy filling, mixing and approximate volume reading while remaining accessible for pipettes, spatulas and pouring. Produced according to DIN 12385, the borosilicate glass 3.3 body offers reliable thermal and chemical resistance for heating, cooling and repeated laboratory use. Nominal volume is 250 ml (0,25 l). The unit is supplied as one piece with a net weight of 0,170 kg, making it a practical choice for individual bench setups, teaching experiments and routine analytical workflows. Its conical geometry supports effective swirling of solutions, and the wide opening eases media transfer and cleaning between runs. Available from manufacturer Labbox, this graduated wide-neck Erlenmeyer integrates into standard glassware collections for titrations, dissolution, buffer preparation and everyday aqueous handling where a robust 250 ml conical flask is required.

Questions about Erlenmeyer flask wide neck, 250 ml, LBG 3.3
What is this article?
Erlenmeyer flask wide neck, 250 ml, LBG 3.3 is the article on this page. Luminix Health distributes Labbox 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.
