摘要: The present invention relates to an apparatus for transferring a liquid capable of accurately performing detection level using pipetting probe even in case high electric conductivity in-flow-passage moving fluid which transmits sucking and discharging operation syringe (107) the (100, 400, 500, 600). has sensing electrode (103, 401, 501, 601) inner tube (102, 402, 502, 602). contacting with be pipetted is electrically separated from filled fluid, both are insulated by insulating member (104B, 403, 503) between them. A container (111) containing held holder (112), can detected change electrostatic capacitance when moved downward. During liquid, not brought contact liquid. grounded.
