| description | The invention relates to the technical field of pipettors, and provides a liquid discharging method of a pipettor. The pipettor is controlled to execute the liquid suction operation before the single liquid discharge operation is executed, so that a section of air column is formed between the liquid in the suction head and the end part of the suction head, and by adopting the liquid discharge mode, on one hand, the movement stroke of the piston can be increased when the single liquid discharge operation is executed; on one hand, the piston can reach a higher limit speed under the limited acceleration to discharge liquid, the liquid discharge precision during single liquid discharge is improved, on the other hand, the liquid in the suction head and the surface tension between the end part of the suction head are basically consistent during each liquid discharge in the process that the pipettor executes multiple liquid discharge operations, and the liquid discharge precision is improved. Therefore, the liquid d |
