NU-427 Class II Type B1 Biosafety Cabinet
The NU-427 Class II Type B1 Biosafety Cabinet by NuAire delivers advanced containment performance with modern digital airflow monitoring and redundancy. Designed as an intermediate solution between recirculating (Type A2) and total exhaust (Type B2) cabinets, the NU-427 ensures user and product protection via constant negative pressure exhaust backed by both mechanical and digital safeguards. Its TouchLink™ control system, digital exhaust flow grid, and downflow air sensor make it ideal for pharmaceutical, biotechnology, and clinical lab applications requiring precise environmental control and GMP-compliant documentation.
Features
- Class II Type B1 Design: Combines partial recirculation with hard-ducted external exhaust
- TouchLink™ Digital Control: Real-time display of inflow, downflow, and exhaust airflow
- Digital Exhaust Flow Grid: Monitors exhaust pressure and calculates exhaust volume
- Downflow Air Sensor: Verifies uniform airflow for product protection
Redundant Safety Systems: Motor interlock and mechanical pressure switch ensure backup if exhaust fails - Performance Logging: On-screen weekly history + 30-day data download via USB
- NSF/ANSI 49 Certified: Fully compliant for biosafety standards
- Dished Work Surface: Retains spills while supporting "clean to dirty" workflow
- External Blower Integration: Designed for connection with facility exhaust system
Applications
- Pharmaceutical Production: Safe handling of APIs and sterile formulations
- Biotechnology Labs: Gene editing, cell culture, and viral vector work
- Clinical Diagnostics: Handling infectious specimens or blood cultures
- Research Laboratories: Protection during toxic or infectious procedures
- Biosafety-Level Work: Appropriate for BSL-2/BSL-3 labs with external exhaust requirements
- GMP-Compliant Environments: Includes data logging for traceability in regulated labs
