Title:
ULTRASONIC PIPETTING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/116461
Kind Code:
A1
Abstract:
An ultrasonic pipetting device, comprising a pipetting module and a control module. The pipetting module comprises an ultrasonic excitation assembly (1), an ultrasonic transducer (2), a coupling device (4), a lens (3), and a liquid carrying device; the ultrasonic excitation assembly (1) is used for exciting the ultrasonic transducer (2) to emit ultrasonic waves; the lens (3) is arranged between the ultrasonic transducer (2) and the liquid carrying device, and is used for changing phase distribution of ultrasonic wavefront so as to enable the ultrasonic waves to be focused at multiple focuses to process a plurality of samples in parallel; a coupling medium in the coupling device (4) is in contact with the liquid carrying device; and the control module is used for modulating excitation parameters of the ultrasonic excitation assembly (1), and the ultrasonic excitation assembly (1) excites the ultrasonic transducer (2) to emit the ultrasonic waves.
