Academy Conical Flask – Narrow Neck 500ml (Borosilicate Glass, ISO 1773)

This high‑quality Academy 500ml Narrow Neck Conical Flask, also known as an Erlenmeyer flask, is manufactured from durable 3.3 borosilicate glass, providing excellent chemical resistance, heat stability, and long‑lasting performance. The flask includes clear printed graduations for easy and accurate measurement during experiments, demonstrations, and practical laboratory work.

Designed to meet the ISO 1773 standard, this flask ensures consistent, reliable performance in both educational and professional laboratory environments. The 38mm internal narrow neck helps minimise evaporation and splashing, making it ideal for swirling, mixing, and heating solutions. It is compatible with a range of 38mm rubber stoppers—available in solid, 1‑hole, and 2‑hole variants—to support a wide variety of experimental setups.
