What is the purpose of a biosafety cabinet?

The primary purpose of a biosafety cabinet is to provide a sterile workspace that protects both the user and the environment from exposure to hazardous biological materials. These cabinets are designed with specialized airflow systems that create a sterile environment by filtering the air and preventing contaminants from escaping. This is especially important when working with biological agents that could pose health risks. The controlled airflow not only ensures that the workspace remains clean and free from external contaminants, but it also protects sensitive samples from being contaminated.

While storing chemicals, holding protective equipment, or displaying biological samples may seem relevant, these functions are not the intended use of a biosafety cabinet. A biosafety cabinet is specifically engineered for safe handling of pathogens and other biological materials, making it a critical component in laboratories that work with potentially hazardous biological entities.
