A distribution apparatus for distributing liquid samples using distribution tips, which distribution tips are held in a tip rack placed in a feeder section and fitted relative to a distribution head. The distribution apparatus has a fitting stage, provided in a space between the feeder section and a distribution stage, for supporting the tip rack and fitting the distribution tips. A distribution tip alignment device is provided in the fitting stage, which aligns dislocated distribution tips at the bottom ends to a correct formation by making contact with the side wall surfaces of the distribution tips. The tip ends of the distribution tips, which are attached to nozzles of the distribution head, are aligned by the distribution tip alignment device at a certain specific pitch, at the time when the distribution tips are attached to the nozzles, or after they are attached to the nozzles. By so doing, a liquid sample can be distributed to small diameter wells without having a dislocation problem.
