Which statement describes proper centrifuge operation?

Maintaining balance in the centrifuge is essential for safe operation and accurate separation. Placing tubes of equal size and volume opposite each other ensures the rotor remains perfectly balanced during spinning. This symmetry prevents vibrations that can damage the rotor and its bearings, reduces the risk of tube breakage or spills, and helps achieve consistent separation of components. The other practices described are unsafe or unnecessary for proper centrifugation: removing stoppers before spinning can cause leaks and aerosol exposure; using different tubes or volumes would create an imbalance unless compensated; and the timing of centrifugation relative to clot formation affects whether you obtain serum or plasma, but it isn’t about safe, balanced operation.
