What’s the usage of dispensing booth

Weighing and subpackaging of powder and reagents in the equipment. It can control the overflow and rise of powder and reagent, and prevent the inhalation hazard of powder and reagent to human body. Also avoid cross contamination of powder and reagents, and protect the external environment and indoor personnel.



Why does the dispensing booth need to maintain a negative pressure environment?


We need to analyze this problem from the purpose of the dispensing booth. The micro negative pressure environment means that the pressure inside the weighing hood is smaller than the external pressure, the air inside the weighing hood will not leak, and the external air flow can enter the weighing hood. In addition to maintaining the micro negative pressure environment in the weighing hood, the wind speed of the air flow in the weighing hood must be strictly controlled. If the wind speed is too high, it will cause the reagent and dust to splash outward, damage the internal dynamic balance, and cannot achieve the effect of isolation and protection.
