PROBLEM TO BE SOLVED: To provide a multiple pipette capable of achieving the reduction of cost and the amount of waste due to the reduction of a chip usage and capable of reducing the troublesomeness of liquid sucking work. SOLUTION: The multiple pipette X is equipped with a first pipette 1 capable of discharging the liquid housed in a liquid holding part 17a from the nozzle 17b connected to the liquid holding part 17a by a constant quantity over many times and a second pipette 2 capable of discharging a liquid sucked from the outside at once. Preferably, the discharge of the liquid by the first pipette 1 is performed through the orifice of the nozzle connected to the liquid holding part 17a and the liquid holding part 17a is made freely detachable. A cap 19 may be attached in a freely detachable manner so as to cover the tip part of the nozzle 17b and, further, in such a case that the concentration of a sample liquid is measured from potential difference generated when a reference liquid with a known concentration and the sample liquid unknown in concentration are short-circuited to each other, the reference liquid is supplied from the first pipette 1 and the sample liquid is supplied from the second pipette 2. |
