A suction tip includes a tip opening, a tubular passage provided with a first selection means configured to permit the passage of non-selection subjects included in a collection of subjects sucked through the tip opening, and a capture means provided on a side of the tubular passage downstream of the first selection means in a suction direction of the collection of subjects and configured to capture the non-selection subjects, and the capture means includes a passage hole configured to permit the passage of the non-selection subjects and a storage portion configured to store the non-selection subjects having passed through. According to the present invention, only impurities having a diameter smaller than a desired diameter can be permitted to pass through the passage hole and stored in the storage portion at the time of suction. As a result, only selection subjects can be discharged by performing only a series of simple operations including suction and discharge. Since these operations do not require an operation of removing the capture means such as a filter, contamination does not occur before and after the operations. |
