Description
Professional Biological Safety Cabinet (Class II Type A2 Biosafety Workstation)
The Professional Class II Type A2 Biological Safety Cabinet is a premium aerodynamic containment workstation engineered to provide simultaneous protection for the operator, the laboratory environment, and sensitive biological samples. Essential for clinical microbiology, molecular biology, virology, and cell culture laboratories, this workstation utilizes a highly calibrated laminar airflow system and dual high-efficiency particulate air (HEPA/ULPA) filtration to prevent exposure to airborne biohazards and cross-contamination.
Key Features & Benefits
1. Comprehensive Three-Way Protection
Engineered to meet strict Biosafety Level (BSL-1, BSL-2, and BSL-3) requirements, the cabinet creates a dynamic air barrier at the front sash. This inflow prevents airborne pathogens from escaping into the room, while a steady downward vertical laminar flow protects your internal samples from cross-contamination, and the exhaust air is fully filtered before release.
2. Advanced HEPA/ULPA Filtration System
Equipped with dual, high-performance filters, the cabinet maintains a pristine Class 100 (ISO 5) cleanroom environment within the work zone. The filtration system captures 99.999% of all airborne particles, bacteria, and viral pathogens down to 0.3 microns, ensuring clean, sterile air recycling.
3. Open-Layout Seamless Work Zone (Without Dividers)
Designed for maximum maneuverability and effortless decontamination, this model features a spacious, flat stainless steel work surface completely without fixed dividers or internal barriers. This uninterrupted, single-piece tray layout allows technicians to arrange vortexers, pipettes, and sample racks freely while preventing liquid accumulation in hidden crevices.
4. Intelligent Microprocessor Control & Safety Interlocks
The digital control center continuously monitors real-time cabinet parameters, including inflow velocity, downflow velocity, and filter lifespan. An integrated safety interlock ensures the internal germicidal UV lamp can only be activated when the front motorized sash is fully closed, preventing accidental UV exposure to laboratory personnel.
