Labglass Conical Flask 3000ml, Narrow Neck – Borosilicate Glass [2651]

The Labglass 3000ml Conical Flask, also known as an Erlenmeyer flask, is a large‑capacity laboratory vessel manufactured from premium 3.3 borosilicate glass. Designed to withstand demanding laboratory conditions, this narrow‑neck flask is ideal for heating, mixing, and handling substantial volumes of liquids in school and college laboratories.

Its conical shape allows efficient mixing by swirling with minimal risk of splashing, while the narrow neck reduces evaporation and enables secure use with rubber stoppers and laboratory fittings. The flask features bubble‑free glass construction, offering excellent resistance to thermal shock and chemical attack. Manufactured to comply with ISO 1773, it provides consistent quality and reliable performance for routine and advanced educational use.

With a very generous 3000ml capacity, this conical flask is particularly well suited to bulk solution preparation, larger‑scale reactions, and teacher‑led demonstrations, making it an essential piece of laboratory glassware for busy science departments.
