TR-TC110W-O Laboratory Mixer with no brush DC motor driver, suitable for Laboratory of low to medium, high viscosity liquid mixing. The machine structure is reasonable and compact, ultra low noise, maintenance free, stirring speed is controlled by the microprocessor, can timely and effective compensation due to changes in load and power supply voltage fluctuation caused by the speed change, constant speed and reliable. Built-in automatic overload protection device, to ensure the continuous operation of the experiment for a long time high load safety; penetration type stirring chuck, expand the types of stir bar experimental application function; digital display stirring speed, ensure experimental visual data acquisition; continuously stirring speed, meet the mixing turn Quick fix; stable mixing speed, high viscosity medium, the size of the mixing.
