Class 2 Biological Safety Cabinet

Class 2 Biological Safety Cabinet are designed to provide triple protection—for the operator, the product, and the environment—making them essential for applications involving sensitive or hazardous materials.

These cabinets utilise a vertical laminar airflow system, where air is drawn into the cabinet, filtered, and directed downward over the work surface to create a sterile working environment. A portion of the air is recirculated while the remainder is safely exhausted, ensuring both containment and product protection.

This controlled airflow prevents contamination entering the workspace while also ensuring hazardous particles are safely contained.

Key Features & Benefits of Class 2 Biological Safety Cabinet

• Protects operator, product, and environment
• Vertical laminar airflow for sterile working conditions
• High-efficiency H14 HEPA filtration (99.995% @ 0.3µ)
• Typically 70% recirculated / 30% exhausted airflow system
• Compliant with BS EN 12469 and NSF 49 standards
• Type tested by UK Health Security Agency (UKHSA)
• Motorised sash and eco mode options available
• Optional heated base plate for temperature-sensitive processes

How It Works

• Air enters through the front opening
• Air is drawn beneath the work surface
• HEPA-filtered air is delivered as downward laminar airflow
• Air is recirculated and partially exhausted through filtration
• Contaminants are contained and prevented from escaping

This ensures a clean, controlled workspace while maintaining operator safety.
