Abstract
To provide a method for calibrating a discharge volume of the pipette that enables accurate measurement of the discharge volume under arbitrary conditions, and to provide an apparatus therefor. The method including the steps of, setting a preset volume by the pipette that is actually used in a measurement (S1), sucking liquid that is actually used in the measurement into the pipette chip that is actually used in the measurement while aiming to be sucked the preset volume (S2), discharging the liquid sucked in the pipette chip onto a measuring apparatus (S3), determining an actual discharge volume of the pipette based on the weight measured (S4 to S6) and calculating a ratio between the preset volume and the actual discharge volume and correcting a sucking amount so as to bring the sucking amount to match an amount obtained by multiplying the preset volume by the ratio (S7 to S9).
