Title: Apparatus for mixing fluids held in tubes

Abstract: A generally upright cylinder is secured at its upper neck by means of a gimbal mount; and its base is driven in circular motion at a substantially constant angular velocity. As a tube of fluid is inserted into the cylinder, the fluid is stirred by the motion of the cylinder; and the intensity of the stirring action increases with the depth to which the tube is inserted into the cylinder. An appliance removably attaches to the apparatus to provide a vibrating platform.
