biological safety cabinet：Essential equipment for laboratory biosafety
Core Functions
Prevention of Aerosol Dispersion: Through negative pressure control and a high-efficiency particulate air (HEPA) filtration system, this system ensures that harmful microorganisms (such as pathogens) generated during experimental operations do not escape from the cabinet, protecting personnel and the environment.
Sample Protection: Outside air enters the cabinet after being filtered by a HEPA filter, creating a clean vertical or horizontal airflow that prevents samples from being interfered with by external contaminants, ensuring the accuracy of experimental results.
Environmental Purification: Contaminated air inside the cabinet is filtered through a HEPA filter before being exhausted, preventing the spread of harmful microorganisms outside the laboratory and reducing public health risks.
