| Hanna Part No: HI-180-schools
The HI-180 series of magnetic stirrers are compact, light-weight and low-cost, yet include our Speedsafe technology for greater control of stirring speed and motor protection. Measuring just 137mm diameter they are available in a range of colours to suit your mood, match your laboratory colour scheme or to differentiate between samples being stirred.
The high specification includes an optical speed control feedback circuit which maintains a constant stirrer speed and limits the maximum speed to 1000rpm even if the load is suddenly removed, thus preventing motor wear and providing a longer operational life.
