Simax Conical Flask Narrow Neck – 1000ml (ISO 1773)

The Simax 1000ml Conical Flask with Narrow Neck, commonly known as an Erlenmeyer flask, is a high‑quality laboratory vessel designed for safe and efficient handling of larger liquid volumes in educational environments. Manufactured from durable borosilicate glass, this flask conforms to ISO 1773, ensuring consistent quality, thermal resistance, and reliability for routine school laboratory use.

With a generous 1000ml capacity and a 39mm internal neck diameter, this flask is ideal for mixing, heating, and swirling solutions while minimising the risk of splashing. The conical shape allows thorough mixing by gentle swirling, making it particularly suited to chemistry experiments that involve reaction observation and solution preparation.

This flask is compatible with 38mm rubber stoppers, including solid stoppers (Product Code 2745), one‑hole stoppers (Product Code 2746), and two‑hole stoppers (Product Code 2747). This versatility allows it to be used in experiments involving gas delivery, tubing, or sealed reactions.
