US 7,726,210 B2 · Sample movement control unit, sample movement parameters acquisition method, and sample movement control method

Abstract

There is provided a device and a method capable of simply manipulating a sample, without the need for an expensive device. A device of the present invention comprises a pipette 4, and vibration section 5, a control section 7 and a storage section 8. At least part of the pipette 4 will be disposed within a liquid 2. The control section 5 causes the pipette 4 to vibrate. The control section 7 supplies vibration signals to the vibration section 5. The storage section 8 stores parameters for generating vibration signals. These parameters include information for generating a first vibrating wave causing a wave motion for drawing a particular sample 3 being within a specified distance from a tip of the pipette 4 to occur within a liquid 2, and information for generating a second vibrating wave causing a wave motion for rotating the drawn in sample 3 to occur. The information for generating the first standing wave and the information for generating the second standing wave are, for example, amplitude and frequency of vibration.
