What type of centrifuge should be used for handling hazardous materials?

In the context of handling hazardous materials, using a safety centrifuge with sealed rotors is essential for ensuring the safe containment of potentially harmful substances. This type of centrifuge is designed to minimize the risk of aerosols and spills that can occur during centrifugation. The sealed rotors provide a barrier that prevents the escape of hazardous materials, thereby protecting both the operator and the laboratory environment from exposure to infectious agents or toxic substances.

Additionally, safety centrifuges often come equipped with features such as automatic lid locks that prevent the centrifuge from operating while the lid is open, reducing the risk of accidents. These safety measures are critical in laboratories where hazardous materials are processed, ensuring compliance with safety regulations and protecting personnel.

The other types of centrifuges mentioned do not provide the same level of containment and safety features required when working with hazardous materials. Therefore, a safety centrifuge with sealed rotors stands out as the appropriate choice in this scenario.
