A heavy solution is stored in a heavy solution reservoir. A sample is separated in a container based on a specific gravity difference with the use of the heavy solution supplied from the heavy solution reservoir. A waste solution from the container is discharged through a first pipe. The heavy solution from the first pipe is sent through a second pipe to the heavy solution reservoir. A filter unit is provided in the second pipe to remove a contaminant from the heavy solution discharged through the first pipe.
