Biological Safety Cabinets (BSCs) are essential laboratory equipment designed to protect personnel, products, and the environment from hazardous biological agents. These devices use HEPA filters and laminar airflow to prevent contamination in the laboratory environment. Different types of BSCs, including Class I (personnel and environmental protection) and Class II A2 (personnel, product, and environmental protection), serve various biosafety needs. Choosing the right model depends on the specific biosafety requirements, features, and the laboratory's budget.
