HI 312N-2

Magnetic stirrer with bi-directional rotation (up to 5 l)

HI 312N-2 is an agitator with large capacity that can shake up to 5 liters. Often to achieve the best results in a test is necessary to reach the maximum homogeneity and solubility of the test sample. To do this you need to shake the liquid in both directions.
HI 312N-2 comes with a circuit of advanced technology that allows you to reverse the direction of shaking at user selected intervals. The intervals can be adjusted from a minimum of 30 seconds to a maximum of 3 minutes. Besides these features, within this stirrer is mounted a speed limiter, which ensures that the latter does not exceed the maximum level.
Often, in fact, in the laboratories are removed samples by agitators before even reduce the speed , causing an acceleration of the motor that causes breakage.
HANNA has included in their agitators a system that stops the acceleration of the motor as soon as you remove the sample (Speedsafe).
Moreover HI 312N-2 has incorporated a system that maintains the constant speed even if the load is changed. In case the viscosity or the level (liquid weight) increases or decreases, the circuit automatically adjusts the power to maintain the speed constant.
