Magnetic Stirrer, Small, Square – Hanna Instruments [0573]

The Hanna Small Square Magnetic Stirrer (HI‑190 series) is a compact, reliable, and cost‑effective solution for stirring liquid samples in school science laboratories. Designed to deliver professional‑level performance without a high price tag, this stirrer is ideal for routine classroom experiments and demonstrations.

With a compact footprint of just 120 × 120mm, the stirrer takes up minimal bench or fume‑cupboard space while still providing consistent and efficient magnetic stirring. Despite its small size, it offers a generous maximum stirring capacity of up to 1 litre, making it suitable for a wide range of laboratory vessels and applications.

The high‑specification design includes an optical speed control feedback circuit, which actively maintains a constant stirring speed even when viscosity or load changes. For added durability, the system also limits the maximum speed to 1000 rpm if the load is suddenly removed, helping to prevent motor wear and ensuring a long operational life. This version is supplied complete with mains cable and plug, ready for immediate use.
