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.

• Dual U15 ULPA Filtration at ISO Class 4: Both the downflow and exhaust filters are U15 ULPA rated at ≥99.9995% @ MPPS, delivering ISO Class 4 cleanliness in the work zone. This directly solves the common pain point of particle contamination compromising sensitive cultures, giving you confidence in your experimental data. For more information on our full range of laboratory instruments, visit our website at Optimum Solution.

• Stable Airflow With Automatic Compensation: The DC ECM blower with Constant Air Volume and Constant Pressure Apheresis System technology automatically compensates for filter loading, maintaining 0.55 m/s inflow and 0.36 m/s downflow. 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.

• Quiet, Energy-Efficient Operation: ECO mode accelerates airflow recovery and lowers power consumption, while noise levels stay as low as 54 dB(A) on the 3-foot model, making long bench sessions more comfortable.

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

• Ergonomic 10-Degree Sloped Front: The sloped front supports a comfortable working posture, and the raised arm rest prevents grille blocking and allows free end-to-end movement.

• 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 valve and pipeline installation.

• Dual UV Timer and Smart Monitoring: Two independent UV timers match different shift patterns, while the 7-inch touchscreen displays velocities, filter life, working hours, ambient conditions, and password-protected settings.

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 airflow drift as filters load? The CAV and CPAS technology continuously compensates for pressure changes, keeping inflow and downflow velocities within safe limits without manual fan adjustment.

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

• Tired of awkward sash handling and slow cleaning? The motorized sash responds to touch, foot switch, or remote, the front window lowers for cleaning, and the tray lifts for access beneath the work area.

• Need compliance with recognized standards? The cabinet meets YY0569, EN12469, 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 containment safety and quiet, efficient operation where it matters most.
