Biological Safety Cabinet Class II B2 LE-BSC403 is designed with a complete 100% exhaust airflow system for maximum contamination control. It is equipped with a robust blower system that delivers steady performance across varying workloads. Integrated air monitoring ensures real-time tracking of airflow conditions for both inflow and downflow. Built-in digital display clearly indicates pressure and airflow parameters for operator assurance. Our Biological Safety Cabinet Class II B2 is ideal for environments where recirculation of filtered air is prohibited, most likely due to the presence of chemical fumes emitted during the process.
