ABSTRACT:
A method and an apparatus for examining and determining the viscosity of a liquid sealed in a container by applying a centrifugal force to the container, detecting a change in the surface form of the liquid with a sensor, and measuring either a lapse of time from the application of centrifugal force to the time when the output voltage of the sensor reaches a predetermined level or a voltage output of the sensor upon a predetermined lapse of time from the application of a centrifugal force, thereby examining and determining the viscosity of the liquid to find out whether there is any quality change in the liquid without destroying the container.
