An analytical solution is presented for the dynamics of small particles of ellipsoidal shape in a liquid, and it is shown particularly on erythrocytes in plasma that it is possible to slow down the vertical free sedimentation 12 000 times or even more, under the condition of suitably selected radius of rotation and angular velocity of the disc. It fully satisfies the requirements of laboratories where various blood measurement are carried out. In the final part of the article a numerical calculation is given for known average values of physical constants of plasma and erythrocytes, the shape and dimensions of the trajectory of particles, centrifugal velocity and a coefficient showing the slowing-down of free sedimentation are determined as well.
