  • Precautions while using Centrifuge

    A ThermoFisher laboratory bench top centrifuge

    Protocols for centrifugation typically specify the amount of acceleration to be applied to the sample, rather than specifying a rotational speed such as revolutions per minute. The acceleration is often quoted in multiples of g, the acceleration due to gravity at the Earth s surface. This distinction is important because two rotors with different diameters running at the same rotational speed will subject samples to different accelerations.
