Class II Type B2 Biosafety Cabinets are high-performance containment systems designed for laboratories handling hazardous chemical vapors or toxic volatile substances along with biological materials. Unlike Type A2 models, Type B2 cabinets feature 100% total exhaust of filtered air without recirculation, making them the preferred choice for applications involving carcinogens, radionuclides, or chemical fixatives.
These cabinets provide triple protection—for personnel, products, and the environment—by combining vertical laminar flow, front airflow barrier, and external ducting. They are widely used in microbiology, molecular biology, pharmaceutical compounding, toxicology labs, and hospital settings.
Key features include:
100% HEPA-filtered exhaust with no recirculated air
Built-in duct connection to external exhaust systems
Suitable for hazardous vapors and chemical-laden procedures
Independent airflow monitoring and automatic safety alerts
Stainless steel work zone and chemical-resistant construction
Class II Type B2 BSCs comply with international biosafety standards such as NSF/ANSI 49 and EN 12469, ensuring maximum containment and laboratory safety. They are ideal for critical research and clinical environments where operator safety and air quality are non-negotiable.
Choose Class II Type B2 Biosafety Cabinets for reliable protection when working with both biological agents and chemical hazards.
