Which type of cabinet is primarily used for working with biohazardous materials?

The Class II biosafety cabinet is specifically designed for working with biohazardous materials and is the most commonly used type in laboratories handling infectious agents. This cabinet provides a sterile environment for the user and protects the materials being handled from contamination, as well as safeguarding the laboratory personnel from exposure to hazardous biological agents. Class II cabinets are equipped with a HEPA filter that effectively captures airborne particles, ensuring both worker safety and product protection.

In addition to its protective features, Class II biosafety cabinets also allow for a wide range of laboratory activities, including manipulation of pathogens, tissue cultures, and molecular biology protocols. Their design supports laminar airflow, which maintains a sterile working environment while also facilitating the safe handling of potentially hazardous biological substances. This makes it a versatile and essential tool for research and clinical laboratories requiring a high level of biosafety.

Other types of cabinets, while they may provide various levels of protection and are used in specific scenarios, do not have the same balance of accessibility, usability, and protection for biohazardous materials as Class II biosafety cabinets.
