<p>There are provided an entire new method for sucking/determining a liquid and a pipetting device driven and controlled by the method in which a liquid level of a liquid sucked by a nozzle, contamination of a liquid with foreign matters, or an interface of a liquid with another liquid having different color are determined by detecting fluctuation of a light obtained from a liquid accommodated in a vessel with a nozzle provided in the nozzle for sucking the liquid, and a liquid level, contamination of a liquid with foreign matters, or an interface of a liquid with another liquid having a different color can be detected with extremely high-sensitivity without being affected by a wavy liquid level by monitoring a pipetting chip or an opening section at a tip of a chip in a cleaning system as if to visually check the other opening section of a tunnel from one side thereof. <IMAGE></p> |
