Laminar air flow cabinet vs Class II biosafety cabinet — airflow, protection, standards (ISO 14644, NSF 49, EN 12469) and when each is required in Indian pharma and research labs.
A laminar flow cabinet protects the product. A biosafety cabinet protects the product, the operator and the environment. If what you are handling could harm a person, you need a biosafety cabinet.
