Introduction: Principles and Practices of Centrifugation
— It is also important to contain the sample during centrifugation, particularly as the samples are often biohazardous or radioactive. Also, the rotors of all ultracentrifuges run in a high vacuum to minimize heating due to air resistance and so it is especially important to isolate the sample, to prevent evaporation, by capping the tubes securely.
