Simax Conical Flask Narrow Neck – 500ml (ISO 1773)

The Simax 500ml Conical Flask with Narrow Neck, also known as an Erlenmeyer flask, is a high‑quality piece of laboratory glassware designed for accuracy, durability, and safe handling in educational environments. Manufactured from premium borosilicate glass, this flask conforms to ISO 1773, ensuring reliable performance for routine school laboratory use.

With a 500ml capacity and a 33mm internal neck diameter, this flask is ideal for mixing, heating, and swirling moderate volumes of liquid. The classic conical shape helps minimise splashing and allows solutions to be mixed efficiently without the risk of spillage, making it suitable for both student experiments and teacher demonstrations.

The flask is compatible with 33mm rubber stoppers, including solid stoppers (Product Code 1165), one‑hole stoppers (Product Code 1476), and two‑hole stoppers (Product Code 1495). This makes it suitable for experiments involving tubing, gas delivery, or temporary sealing.
