The erythrocyte sedimentation rate in inclined tubes

In this investigation, the erythrocyte sedimentation rate was studied in inclined tubes. Two parameters were included which make this work different from any previous research on this subject. First, the actual rate of settling was measured with an automatic sedimentimeter and second, the settling tubes were rotated along their long axis with constant angular velocity. The results in both the vertical and inclined tubes could be expressed in terms of a simple mathematical equation. It was also observed that the rotation of the inclined tubes practically negates the effect of the inclination.
