Played a vital role in virology because it provides sufficient gravitational force to efficiently sediment even the smallest viruses



Rate Zonal Centrifugation

Sample is layered as a narrow zone on the top of a density gradient, under centrifugal force, particles move at different rates depending on mass


Buoyant Density

Object has exactly the same density as the fluid, remains submerged in the fluid but will neither sink or float


Isopycnic Point

Point where the buoyant density of a particle equals that of the surrounding density gradient medium


Isopycnic Centrifugation

Particles are separated solely on the basis of their buoyant density, the particles will never sediment to the bottom of the tube, no matter how long the centrifugation time


Membrane Chromatography
