Final answer:
If a centrifuge shakes too much, it can result in sample loss or contamination, damage to the centrifuge, and potential instability.
Step-by-step explanation:
When a centrifuge shakes too much, it can lead to several problems. Firstly, the samples being centrifuged can become dislodged or spill out of their containers, leading to a loss of experiment or contamination. Secondly, the excessive shaking can cause damage to the centrifuge itself, such as loosening or breaking of parts. Lastly, if the centrifuge is not properly balanced, the shaking can become even more severe, potentially causing the centrifuge to tip over or become unstable.
