PURPOSE: To control the inclination operation of a container with the same amount of precision as manual operation by providing a retention arm and a rotary handle at the center of two large and small discs which are in contact with each other on the circumferential surface. ;CONSTITUTION: It is desirable that the ratio of diameter of a large disc E to that of a small disc F with extremely different radii of curvature should be 10:1-100:1. The discs E and F are in contact at the side surfaces with each other. Then, when a handle G at the center of the disc F is rotated to rotate the disc F, the disc E with a large diameter than that of the disc F gradually and smoothly rotates. The slow rotary motion is transferred to a container retention tool C which retains a container B being provided at the tip of a retention arm J by the retention arm J. Therefore, the rotation of the handle G causes the container B to be inclined slowly and smoothly and hence a supernatant liquid to flow out quietly and to be separated from a precipitate. Namely, arbitrary rotary control of the handle G enables the container B to be inclined at arbitrary speed and angle and hence achieving the same amount of decantation of a sample as that by manual operation.;COPYRIGHT: (C)1994,JPO&Japio
