The Biosafety Cabinet is a laboratory containment enclosure designed to protect the operator, environment, and samples while handling biological materials, microorganisms, and hazardous aerosols. It uses HEPA-filtered laminar airflow and negative pressure containment to prevent contamination and exposure. Widely used in microbiology, pharmaceutical, clinical, and research laboratories, the cabinet ensures a sterile working environment for culture handling and sample preparation. With ergonomic design, low noise operation, and reliable filtration efficiency, it provides safe and compliant laboratory working conditions.
