Abstract
A valve bridge portion, in which four valves A to D are connected in a bridge shape, is interposed between sample lines to a rotor of a continuous centrifuge. A microcomputer is able to open and close the valves A to D independently and is capable of switching between top feed and bottom feed to the sample line. When sample supply is started, switching between the top feed and the bottom feed is performed multiple times, and in the middle of switching and sending a sample liquid, the microcomputer executes an operation of temporarily increasing a liquid pressure multiple times by temporarily closing an outlet valve (C or D) and then immediately opening the valve. As a result of repeating the operation of switching between the said sample feed directions and temporarily increasing the liquid pressure, air that accumulates inside the rotor can be effectively discharged.
