Analytical ultracentrifugation is a classical method of research in biochemistry, molecular biology and polymer physics. During centrifugation, the process of sedimentation (precipitation) occurs (deposition of macromolecules and/or colloidal particles in solution under the influence of centrifugal forces). Ultracentrifuge was created by Swedish physical chemist Nobel Prize winner T. Svedberg specifically to create bigger, than gravity, the sedimentation force to affect the particles dissolved in the solution. This experimental setup consists of a rotor that spins around its axis with high constant speed, the cell with solution which is placed at the distance from the rotation axis. Centrifugal force directed radially from the axis of rotation, resulting in the motion of the particles and the velocity of the particles sedimentation in solution allows to estimate their molecular weight.
