Product Introduction
The biological safety cabinet is a box‑type air‑purifying negative‑pressure safety device that prevents aerosol escape of hazardous or unknown biological particles during experimental operations. Its working principle is mainly to draw air outwards to maintain negative pressure inside the cabinet, and protect operators by means of vertical airflow. It is widely applied in biomedicine, food, inspection and testing, inspection and quarantine, agriculture, forestry, animal husbandry and fishery, environmental protection, scientific research and other fields.
