Biological Safety Cabinets

Biological Safety Cabinets (BSCs) are essential laboratory equipment designed to provide protection for users, samples, and the surrounding environment when handling potentially infectious or hazardous biological materials. Widely used in microbiology, clinical diagnostics, biotechnology, and pharmaceutical research, BSCs are critical for maintaining sterile conditions and minimizing the risk of cross-contamination.


Our product range includes two main types of Class II biosafety cabinets to meet various application needs:

  • Class II Type A2 Biosafety Cabinets: Ideal for general microbiological work, these cabinets offer 70% air recirculation and 30% HEPA-filtered exhaust. They are suitable for handling low- to moderate-risk biological agents and ensure comprehensive protection for personnel, products, and the laboratory environment.

  • Class II Type B2 Biosafety Cabinets: Designed for high-risk procedures involving chemical vapors or volatile toxic substances, these cabinets offer 100% HEPA-filtered total exhaust without air recirculation. They are connected to an external ventilation system and are ideal for labs working with carcinogens, radionuclides, or hazardous chemicals.


All our biological safety cabinets comply with international standards (such as NSF/ANSI 49 and EN 12469) to ensure top-tier containment, reliability, and performance. Whether you're running routine biological experiments or conducting high-risk pathogen research, our BSCs provide a safe, compliant, and efficient working environment.
