Biological Safety Cabinets Have Two Exhausts
ADS Laminaire BIO II 9 and 12 Class II, Type A2 Biological Safety Cabinets available from Dynalon provide personnel, product and environmental protection from hazardous particulates. Biological safety cabinets are used in cell culture, diagnostic, biotechnology and pharmaceutical, clinical and microbiological applications. These cabinets meet ISO 5 (Class 100) requirements. During operation, room air is drawn into the inlet grill at the work access opening and through a HEPA-rated filter. Approximately 70% of the HEPA-filtered air is circulated through the cabinet, while 30% passes through a second exhaust HEPA filter and is discharged. These biohazard cabinets are designed to discharge HEPA-filtered exhaust air directly into the laboratory. The BIO II 9 model is suited for small rooms because of its efficient design. BIO II cabinets are available in 3 and 4’ width.
