Abstract
The present invention is a liquid processing method making use of a pipette device which sucks a liquid containing a target high molecular substance from inside of a vessel through a chip detachably set on a sucking port or a discharging port of a liquid sucking/discharging line and transfers this liquid or target high molecular substance to the next target processing position for the purpose to execute such works as quantifying, separating, taking out, pipetting, clarifying, condensing, and diluting a liquid or a target high molecular substance contained in a liquid and also such works as extracting, recovering, and isolating the target high molecular substance by means of sucking and discharging a liquid with a pipette device and controls by a magnetic body over magnetic particles and/or a filter combined according to the necessity, and the chip can isolate the target high molecular substance by having the substance attracted onto magnetic particles or with a filter set on each chip.
