Abstract
An apparatus is described with which electric potentials, developed as a result of phenomena occurring in the rotor of a centrifuge, can be measured within one microvolt, and radial temperature differences in the rotor can be determined and controlled within 0.01°. Rotation in a vacuum minimizes the rise of temperature of the rotor, which can also be measured. The speed of rotation is controlled by a friction drive within 0.01 percent and maintained at definite values, between 400 to 7200 r.p.m., corresponding to stroboscopic patterns. The instrument was designed to measure the effect of centrifugal fields on simple galvanic cells.Keywords
