Abstract: A dispensing device that dispenses a liquid sample with a target weight x (in grams) includes: a pipette that discharges the liquid sample into a vessel; and a controller that controls the pipette. The controller performs: first liquid discharge processing in which the controller discharges the liquid sample with a volume of (x/ρ0×y) milliliters (mL) into the pipette, where y is a numeric value greater than 0 and smaller than 1, and ρ0 is the tentative density (in grams per mL) of the liquid sample; first weight acquisition processing in which the controller acquires information about the weight z (in grams) of the liquid sample discharged in first liquid discharge processing; density calculation processing in which the controller calculates the density p (in grams/mL) of the liquid sample according to the expression ρ=z/(x/ρ0×y); and second liquid discharge processing in which the controller discharges, into the pipette, the liquid sample with a volume based on the density ρ, weight z, and target weight x.
