A Biosafety Cabinet is a specialized workspace designed to protect users, the environment, and samples from contamination. It uses a combination of airflow and filtration systems to create a sterile environment, making it essential for handling hazardous biological materials, such as bacteria and viruses. These cabinets are classified into different levels, such as Class I, Class II, and Class III, based on their design and the level of protection they provide. They are commonly used in laboratories, hospitals, and research facilities to ensure safe handling of potentially dangerous substances while maintaining a clean workspace.
