Labglass Conical Flask 5000ml, Narrow Neck – Borosilicate Glass [2652]

The Labglass 5000ml Conical Flask, also known as an Erlenmeyer flask, is a large‑capacity laboratory vessel manufactured from premium 3.3 borosilicate glass. Designed for strength, durability, and thermal stability, this narrow‑neck flask is ideal for heating, mixing, and handling very large volumes of liquids in educational and laboratory environments.

Its classic conical shape allows efficient mixing by swirling while minimising the risk of splashing, even with high fill volumes. The narrow neck helps reduce evaporation and improves control when pouring or fitting stoppers. The flask’s bubble‑free construction provides excellent resistance to thermal shock and chemical attack. Manufactured to conform with ISO 1773, it delivers reliable, consistent performance for demanding laboratory use.

With a substantial 5000ml (5 litre) capacity, this conical flask is particularly suitable for bulk solution preparation, large‑scale reactions, and whole‑class demonstrations, making it an essential item for well‑equipped school and college science laboratories.
