The Biological Safety Cabinet is engineered to eliminate these risks. As a cornerstone of the Biological Safety Cabinet series, this Class II Type B2 unit is built for microbiological research, pharmaceutical development, clinical diagnostics, and tissue culture laboratories that require uncompromising total-exhaust containment. This Biological Safety Cabinet provides a reliable, validated work environment with 100% exhaust airflow, U15 ULPA supply filtration, and H14 HEPA exhaust filtration, so that all air passing through the work zone is discharged from the building rather than recirculated. We understand that in your line of work, total-exhaust containment reliability is not just a feature—it is a safety necessity.

Key Benefits: Precision, Efficiency, and Safety for Your Lab

Our Biological Safety Cabinet is more than just a piece of equipment; it is a solution designed to address the real-world challenges you face daily. We have focused on core features that deliver tangible benefits, enhancing your lab's safety and the reliability of your containment work.

• 100% Total-Exhaust Containment: All air passing through the work zone is discharged from the building through the exhaust filter, with no recirculation into the room. This directly solves the common pain point of chemical vapor and radionuclide recirculation, giving you confidence when handling volatile or hazardous materials. For more information on our full range of laboratory instruments, visit our website at Optimum Solution.

• Dual High-Efficiency Filtration: A U15 ULPA downflow supply filter (≥99.9995% @ MPPS) delivers ISO Class 4 cleanliness, while the H14 HEPA exhaust filter (≥99.995% @ MPPS) protects the environment, both conforming to EN1822. This engineering excellence reflects the manufacturer's commitment to biosafety standards, and you can view the product page on the manufacturer's site for additional technical resources and application notes.

• Energy-Efficient DC ECM Blower: The advanced DC ECM blower with Constant Air Volume and Constant Pressure Apheresis System technology maintains safe airflow as filter resistance changes, while ECO mode shortens airflow recovery time and lowers power consumption.

• Motorized WiseSash Design: The electric sash operates by touch screen, foot switch, or remote controller, with an independent manual sash system that can be shut down during power failure and UV-proof glass protecting people during disinfection.

• WiseClean and WisePort Convenience: The front window lowers for cleaning, the work tray lifts and is supported by a rod for access beneath the tray area, and WisePort fittings on both side walls allow flexible installation of valves and pipelines.

• Comprehensive Smart Monitoring: The 7-inch touchscreen displays downflow velocity, inflow velocity, differential pressure, ambient temperature and humidity, UV working time, filter working time, and filter life percentage, with dual UV timers for flexible shift matching.

• Full Alarm Coverage: Visible and audible alarms for inflow velocity, downflow velocity, sash height limit, high filter resistance, fan failure, and filter life alert keep operators informed of any condition requiring attention.

Solving the Problems That Slow Lab Work Down

We know the frustrations that come with daily biosafety cabinet operation. The Biological Safety Cabinet is built to eliminate them.

• Struggling with recirculated vapors from chemical or radionuclide work? The 100% exhaust airflow pattern discharges all work zone air outside the building through the HEPA exhaust filter, eliminating recirculation risk.

• Concerned about filter condition and replacement timing? The WiseFlow control system displays filter life percentage and working time, triggering alarms for high resistance and filter life so you always know your cabinet is safe to operate.

• Tired of awkward sash handling during loading and cleaning? The motorized sash operates by touch screen, foot switch, or remote, the front window lowers for cleaning, and the work tray lifts for access beneath the tray area.

• Need compliance with recognized standards? The cabinet meets YY0569 and NSF49, with operator, product, and cross-contamination protection verified against accepted microbiological test methods. For more information on NSF/ANSI 49 biosafety cabinet standards, visit the NSF International website.

By choosing this Biological Safety Cabinet, you are investing in a dependable partner for your lab's daily operations, designed to deliver total-exhaust containment safety and reliability where it matters most.
