Laboratory emulsifier and laboratory disperser motor are brush type, need to regularly check brush wear, under normal circumstances brush left about 6 mm need to be replaced. When replacing the brush, it is necessary to cut off the power supply, unscrew the brush cover, extract the remaining brush, insert the new brush into the tube to move freely, prevent rolling in the tube, cause sparks or motor not running, unscrew the brush cover.

After the work is finished, the cutter shaft should be cleaned in time to facilitate the next use. The cutter shaft should be properly placed and must not fall.
The laboratory homogenization process should be carried out in the liquid medium, and it is strictly prohibited to leave the medium for idling. Laboratory emulsifier and laboratory dispersing machine are not suitable for solid dispersion.

Laboratory emulsifier and laboratory dispersing machine must be placed in a dry and clean place, keep clean and keep moisture away. The ambient temperature is generally not more than 40 degrees Celsius.
