Biological Security Cabinets Purifier® Logic + ™
Purifier Logic+ Class II, Type A2 Biosafety Cabinets (BSCs) provide personnel, product, and environmental protection from hazardous particulates such as agents that require Biosafety Level 1, 2, or 3 containment, as well as antineoplastic drugs, genetic material, carcinogens, allergens, and other substances that generate hazardous airborne particulates.
The cabinets feature a unique airflow pattern to achieve personnel and product protection. During operation, room air is drawn into the inlet grille at the work access opening and filtered through a supply HEPA filter.
Approximately 70% of the HEPA-filtered air is then circulated back into the cabinet, while the remaining 30% passes through an exhaust HEPA filter and is discharged to the lab or optional canopy. This recirculation of filtered air ensures the user, product, and lab are adequately protected from hazardous particulates.
