What happens if a centrifuge is not balanced?

• A. Tubes break
• B. Gases accumulate
• C. Filtration fails
• D. Temperature rises

Answer: (A)

When a centrifuge is not balanced, the mass in the rotor is not evenly distributed around the axis, so the centrifugal forces act unevenly. This creates large lateral forces and vibration because the rotor is trying to accelerate a heavier side more than the opposite side. The most immediate and dangerous consequence is stress on the tubes and rotor, which can cause tubes to crack or rupture at high speed. A tube rupture is a common catastrophic outcome because the violent motion and stress from the unbalanced load can exceed the tubing’s strength. While unbalance can also cause bearing wear or overheating over time, the defining, most likely failure in this scenario is the tubes breaking. Keeping loads balanced and using equal volumes in all tubes helps prevent this. If imbalance is detected, the machine should be stopped and the load inspected before resuming.
