Negative pressure weighing booth is a kind of partial purification equipment specially used for pharmaceutical, microbiological research and scientific experiments area. It provides a vertical unidirectional airflow, part of the clean air circulates in the work area, and part is discharged to the nearby area, so that the work area can generate negative pressure, prevent cross-contamination, and ensure a high cleanliness environment in the work area. Making the weighing and packaging of dust and reagents in the equipment can control the overflow and rise of dust and reagents, prevent the inhalation hazards of dust and reagents to the human body, and also avoid cross-contamination of dust and reagents, and protect the safety of the external environment and indoor personnel.
