Overhead (powerful) electric mixers are suitable for mixing medium to high viscosity liquids. The LCD overhead stirrer is more high-end and safer than the LED series. Self-locking chuck is adopted, and square lifting and fixing clips are independently developed. For solid-liquid, liquid-liquid or medium to high viscosity sample mixing. Mainly used in chemical synthesis, pharmaceuticals, physical and chemical analysis, petrochemical, cosmetics, health products, food, biotechnology and other fields. The product is capable of high load and long-time continuous work with outstanding performance. With overload and abnormal situation automatic protection function, to ensure the safety of the laboratory.

Features

●LCD display, the speed and time can be roughly adjusted, and the working time can also be fine-tuned in the working state;

●Speed 30-2200rpm, constant speed, high-low speed controllable;

●Using DC brushless motor, it can run safely for a long time and has outstanding performance;

●Overload and motor protection, in the event of overload, short circuit or abnormality, the circuit will be automatically cut off and an alarm will be issued to ensure the safety of the experiment;

● Equipped with a stirring paddle penetration hole, the user does not need to adjust the installation height of the instrument, only the installation position of the stirring rod is sufficient;

The torque can be automatically adjusted according to the viscosity change of the sample, which is convenient for experimental operation;

●A variety of stirring paddles and brackets are optional.
