Biological Safety Cabinet Class II B2 LE-BSC401 is designed with 100% exhaust airflow and leak-free construction. It is equipped with a high-performance blower that ensures consistent and contamination-free operation. Integrated air velocity monitoring system maintains real-time control over inflow and downflow. Built-in pressure sensor displays negative pressure differentials accurately on a large LCD. Our Biological Safety Cabinet Class II B2 is designed to provide operator, product, and environmental protection in environments where recirculation of filtered air is prohibited.
