Academy Conical Flask – Narrow Neck 100ml (Borosilicate Glass, ISO 1773)

This high‑quality Academy 100ml Narrow Neck Conical Flask, also known as an Erlenmeyer flask, is manufactured from durable 3.3 borosilicate glass for outstanding chemical resistance, thermal stability, and long‑lasting laboratory performance. Designed with clear printed graduations, it allows for easy and accurate measurement of liquids during experiments and demonstrations.

Complying with the ISO 1773 standard for conical laboratory flasks, this flask offers dependable reliability for both educational and general laboratory use. It features a narrow neck with an internal diameter of 30mm, making it ideal for minimising evaporation and splash‑out during mixing or swirling. It is compatible with 29mm (bottom) rubber stoppers — suitable matches include product codes 1158, 1162, and 1493.
