For many chemical laboratories, there are more or less traces of chemical leakage and poor ventilation. This directly leads to high laboratory odor and high VOC concentration, which can be equipped at indoor volatile sources. The movable universal exhaust hood will greatly improve the indoor environment, restore clean air in the laboratory, and protect the physical and mental safety of chemical laboratory workers.

Principle and schematic
The inside of the cabinet is equipped with a fan and a filter. The fan draws the wind at the volatilization source into the filter device of the tank through the suction hood and the pipeline, and the clean air after the filtration is directly discharged into the room.
Application range
  All volatile sources with local volatility, such as chemical operation, volatilization during the working process of the instrument, soldering, etc.
Dissolution, mixing, stirring, pipetting, sampling, PH testing, Kjeldahl, HPLC , GC-MS , LC-MS...
The filter has strong adsorption capacity for organic solvents, acids, bases, perfumes, pesticides and the like.
