Abstract
The apparatus of the present invention can be used to measure sedimentation rate of samples. The samples are placed in a sample rotor and are rotatable about a sample rotor axis. The sample rotor axis can be moved into two positions. In one position the sample rotor axis is substantially horizontal and in the other position the sample rotor axis is substantially vertical. Rotation of the sample rotor about the sample rotor axis causes stirring of the samples when the sample rotor axis is horizontal. When the sample rotor axis is substantially vertical settling of the samples occur. Step rotation of the sample rotor brings the samples to a reading means in order to analyze the samples. An optical signal sensor moves along the sides of the test tubes for measuring the sedimentation rate.
