Abstract

Provided is a pipette device that can discharge or withdraw a liquid easily by liquid processing operation by a robot device. Provided is a pipette device held by a robot device, comprising a driving part for withdrawing and/or discharging a liquid, a signal receiving part for receiving a signal from the robot device and a control part for controlling the driving part according to the signal.

First claim

1 . A pipette device held by a robot device, comprising
a driving part for withdrawing and/or discharging a liquid, a signal receiving part for receiving a signal from the robot device, and a control part for controlling the driving part according to the signal.

2 . The pipette device according to claim 1 , comprising
a tip connecting part for connecting a tip to be in contact with the liquid, an information acquiring part for acquiring information on the position of the tip in the state where it is connected to the tip connecting part and information on the state of the driving part, and a signal transmitting part for transmitting the information on the position of the tip and the information on the state of the driving part to the robot device.

3 . The pipette device according to claim 2 , wherein
the driving part has a plunger and the information on the state of the driving part includes information on the position of the plunger.

4 . The pipette device according to claim 2 , wherein
the information on the position of the tip is based on the distance between the tip and any one or more articles present in the range in which the tip is movable by the robot device.

5 . The pipette device according to claim 2 , wherein
the information acquiring part has an internal pressure sensor for detecting the pressure applied into the tip.

6 . The pipette device according to claim 2 , wherein
the information acquiring part has a pressure sensor for detecting the pressure applied to the surface of the tip connecting part in contact with the tip.

7 . The pipette device according to claim 2 , wherein
the information acquiring part acquires the information on liquid state, and the signal transmitting part transmits the information on liquid to the robot device.

8 . The pipette device according to claim 2 , wherein
the rate of withdrawing the liquid into the tip and/or the rate of discharging the liquid contained in the tip from the tip are/is controlled based on the signal and the information on the state of the driving part.

9 . The pipette device according to claim 1 , wherein
the timing of the liquid withdrawal and/or discharge is controlled by the signal.

10 . The pipette device according to claim 1 , wherein
the control part controls the driving part by radio communication.

11 . A liquid processing system having a robot device and a pipette device held by the robot device, the pipette device comprising
a driving part for withdrawing and/or discharging a liquid, a signal receiving part for receiving a signal from the robot device, and a control part for controlling the driving part according to the signal.

12 . The liquid processing system according to claim 11 , wherein
the pipette device additionally comprises
a tip connecting part for connecting a tip to be in contact with the liquid,
an information acquiring part for acquiring information on the position of the tip in the state where it is connected to the tip connecting part and information on the state of the driving part, and
a signal transmitting part for transmitting the information on the position of the tip and the information on the state of the driving part to the robot device, and
the operation of the robot device is controlled based on the information on the position of the tip and the information on the state of the driving part.

13 . The liquid processing system according to claim 11 , wherein
the robot device has an arm part, and the arm part has multiple joints.

14 . The liquid processing system according to claim 13 , wherein
the robot device has a control panel and a computer.

15 . The liquid processing system according to claim 14 , wherein
the computer comprises one or more parts selected from the group consisting of an input part, a signal transmitting part, a signal receiving part, a display part, a control part, and a memory part.
