Abstract

In the preparation of blood films for microscopic examination a slide spins in a centrifuge for a time which is a function of the red blood cell concentration of the blood. A drive circuit controls the time of spinning of a slide centrifuge. A variable control for the centrifuge motor includes a manual adjustment which is adjustable across a scale labeled as a function of the percent hematocrit of the blood.
