PURPOSE:To easily draw, spot and supply a sample liquid and reference liquid by making a pair of pipettes freely movable in a horizontal direction to vary the distance therebetween and making the pipettes vertically movable when the spacing therebetween is smaller than the prescribed spacing. CONSTITUTION:A disk 50 is rotated to move both pipettes 1, 3 from a tight contact position to an open position. The spacing between dropping tips 6, 6 increases and the suction of the sample or reference liquid contained in a reagent bottle, etc. by immersing only the one tip 6 into the reagent bottle is made easy in the stage of sucking the sample or reference liquid. A push rod 21 and piston rod 23 are moved upward by the energizing force of upper and lower coil springs 25, 26 when the bottom end of the tip 6 is lower coil springs 25, 26 when the bottom end of the tip 6 is immersed into the liquid in the reagent bottle and the hand is released from the rod 21 after the rod 21 is pushed down to move the rod 23 downward. The liquid is then sucked into the tip 6. The prescribed liquid is similarly sucked into the other tip 6 as well. The disk 50 is then rotated to move the pipettes 1, 3 to the tight contact position. The sample liquid and reference liquid are simultaneously spotted and supplied when the bottom ends of the tips 6, 6 are disposed to face each of a pair of the liquid spotting holes and the two push rods 21, 41 are simultaneously pushed down.
