PURPOSE:To present solution from remaining on a tip of a chip to obtain a dispenser with improved accuracy. CONSTITUTION:When a predetermined amount of liquid sample has dripped from a tip of a chip 14, a piston 10b of a syringe pump 10 is pulled down to have suction performed, whereby liquid sample which may possibly remain is dripped down to prevent liquid from becoming a liquid ball at the tip of the chip 14. Thus liquid sample residue on the tip of the chip 14 can be prevented to improve measurement accuracy. |
