The AD500S-H laboratory dispersion homogenizer is driven by a compact series of miniature high-speed motor. It is suitable for mixing and mixing low to medium and high viscosity liquids in the laboratory, dispersing homogeneous particulate materials in liquid medium, breaking tissue cells, etc. . The machine consists of a high-speed motor, a decentralized homogenizing head and a speed controller. The driving host adopts high-quality engineering plastics and die-casting aluminum alloy as the body, and the running state is stable; the working head is made of high-quality stainless steel, and the experimental application area is wide; the running speed is controlled by the microprocessor, which can instantly compensate the load change and the power supply voltage fluctuation effectively. The speed change caused by the constant speed is reliable; the built-in soft start and automatic overload protection ensure the safety of the continuous operation of the test at full load for a long time; the stepless adjustment of the speed meets the correction of the speed at any time in the experiment. The product has been upgraded, with the drive host power, high speed, pre- or dynamic set speed, pause and restart can remember the original speed and other functions.
