Academy Conical Flask – 50ml Narrow Neck (Borosilicate Glass)

The Academy 50ml Conical Flask, also known as an Erlenmeyer flask, is part of a new, affordable, and high‑quality range of laboratory glassware designed specifically for educational use. Manufactured from durable 3.3 borosilicate glass, this narrow‑neck flask offers excellent performance for heating, mixing, and safely handling liquids in school science laboratories.

Featuring clear graduation markings for approximate volume measurement, the flask is designed with a narrow 26mm neck to reduce splashing and evaporation when swirling solutions. Borosilicate glass is well known for its superior chemical resistance and high heat tolerance, allowing the flask to withstand rapid temperature changes and repeated classroom use. The flask complies with the ISO 1773 standard, ensuring consistent quality and reliability.

Compact yet versatile, this 50ml conical flask is ideal for student experiments, demonstrations, and technician preparation work where smaller volumes are required.
