Why is centrifugation at high speeds carried out in a near vacuum?
A)to maximize frictional resistance to the rotor's motion
B)to minimize frictional resistance to the rotor's motion
C)to balance the rotor
D)to stabilize the rotor
E)to minimize pH fluctuations

Question

Quizplus · Accepted Answer

Centrifugation at high speeds generates a lot of heat due to frictional resistance between the rotor and the air. This can cause the rotor to overheat, potentially damaging the sample or the equipment. By carrying out the centrifugation in a near vacuum, the frictional resistance is minimized, reducing the generation of heat and preventing damage to the rotor and the sample.
