Academy Conical Flask – 1000ml Narrow Neck (Borosilicate Glass)

The Academy 1000ml Conical Flask, also known as an Erlenmeyer flask, is part of a new, affordable, and high‑quality range of laboratory glassware developed for educational and laboratory use. Manufactured from durable 3.3 borosilicate glass, this large‑capacity, narrow‑neck flask is ideal for mixing, heating, and storing larger volumes of liquids in school science laboratories.

Designed with a 35mm narrow internal neck diameter, the flask helps reduce spillage and evaporation when swirling solutions. Clear graduation markings allow for approximate volume measurement, supporting accurate classroom experiments and demonstrations. Borosilicate glass offers superior resistance to chemicals and high temperatures, making this flask suitable for repeated use with Bunsen burners or hot plates. The flask is manufactured to comply with the ISO 1773 standard, ensuring reliability and consistent quality.

With its generous 1000ml capacity, this conical flask is ideal for whole‑class demonstrations, solution preparation, and advanced student experiments.
