HEPA filters are one of the most crucial components of any biosafety cabinet, it ensures that harmful airborne particles are trapped before they can contaminate samples, expose laboratory personnel, or escape into the environment. Even though these filters are set to achieve an efficiency of 99.97% for particles as small as 0.3 microns, they are …
A biosafety cabinet is a ventilated enclosure used in laboratories and designed to protect laboratory personnel, research samples, and the surrounding environment from biological contamination. The best equipment for labs depends on the type of research, biosafety level, airflow requirements, and the category of cabinet. Laboratories working with infectious agents, cell cultures, pharmaceuticals, and microbiological …
