What is a recommended action after using a centrifuge for biological samples?

After using a centrifuge for biological samples, inspecting for leaks is crucial as a recommended action. This step ensures that no samples or potentially hazardous materials have leaked out during the centrifugation process. Biological samples can contain infectious agents or harmful substances, and identifying leaks can prevent contamination and exposure to these biological hazards.

Additionally, inspecting for leaks helps maintain the integrity of the samples themselves by ensuring that their contents remain safe and usable for further analysis. This action is a key part of lab safety procedures that emphasize proper handling and management of biological materials.

Waiting for a signal or cleaning the outside may be relevant actions but do not directly address the risk associated with the contents of the centrifuge. Opening the centrifuge immediately could also pose a risk of aerosolization or exposure to contaminants. Hence, checking for leaks first aligns with best practices in lab safety and biological sample handling.
