Class 3 Biological Safety Cabinet

This Class 3 Biological Safety Cabinet delivers maximum containment and protection, making them the ideal solution for handling high-risk biological agents (up to Hazard Group 4).

Unlike open-front cabinets, Class 3 units are fully enclosed and gas-tight, with operators working through sealed glove ports. Air entering the cabinet is filtered before reaching the workspace, and all exhaust air passes through double HEPA filtration, ensuring complete containment of hazardous materials.

This design provides the highest level of safety for critical environments where absolute containment is required.

Key Features & Benefits of Class 3 Biological Safety Cabinet

• Maximum containment with fully enclosed design
• Protects operator, product, and environment
• Gas-tight construction with glove port access
• Double H14 HEPA filtration (99.995% @ 0.3µ)
• Suitable for Hazard Group 4 (HG4) materials
• Compliant with BS EN 12469 and NSF 49 standards
• Type tested by UK Health Security Agency (UKHSA)
• Available in standard, double chamber, and double-sided configurations

How It Works

• Air is drawn into the cabinet through HEPA filtration
• Clean air enters the fully enclosed work chamber
• Air circulates within the sealed environment
• Exhaust air passes through double HEPA filters
• Contaminants are fully contained with no exposure risk

Operators interact with materials via integrated glove ports, ensuring a complete physical barrier between user and hazardous substances.
