Cell picking device and cell picking method

A cell picking device for sucking cells from a liquid sample in a sample container, comprising:

• a sucking member to which a pipette tip is attachable;
• a driver that moves the sucking member and performs suction through the sucking member and the pipette tip;
• a work mode switcher that switches a work mode of the driver between a first mode and a second mode;
• and
• a controller that controls the driver, wherein
• the controller, in the first mode, controls the driver such that first advancing work for bringing an end of the pipette tip into contact with a bottom surface in the sample container by causing the sucking member to advance in an axial direction of the pipette tip with the pipette tip, attached to the sucking member, being tilted with respect to a vertical direction, scanning work for scanning the bottom surface of the sample container toward a first position using the end of the pipette tip by moving the sucking member in a horizontal direction, tilting work for lifting the end of the pipette tip and lowering a base of the pipette tip in the first position by tilting the sucking member further with respect to the vertical direction, and sucking work for sucking a sample in the sample container through the sucking member and the pipette tip, are performed, and
• in the second mode, controls the driver such that second advancing work for causing the end of the pipette tip to advance to a second position farther upward than the first position in the sample container by causing the sucking member to advance in the axial direction of the pipette tip with the pipette tip, attached to the sucking member, being tilted with respect to the vertical direction, and the sucking work are performed.
