Title:
ULTRASONIC PIPETTING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/004795
Kind Code:
A1
Abstract:
The present invention provides an ultrasonic pipetting apparatus, comprising an ultrasonic emission module and a liquid-carrying apparatus; the ultrasonic emission module comprises a multi-probe component, a coupling liquid circulation system and an ultrasonic excitation component, the liquid-carrying apparatus being disposed above the multi-probe component; the multi-probe component comprises two or more probes, a coupling cavity and a coupling nozzle, wherein the two or more probes are disposed on the same support, the liquid-carrying apparatus is provided with multiple liquid-carrying holes, the focal point of the probes is aligned with the liquid level of the liquid-carrying apparatus, the coupling cavity surrounds the probes, the coupling nozzle is disposed between the probes and the liquid-carrying apparatus, and the coupling cavity is internally filled with a coupling liquid; the coupling liquid circulation system enables the coupling liquid to continuously enter the coupling cavity, and the coupling liquid overflows from the coupling nozzle to make contact with the bottom part of the liquid-carrying apparatus; and the ultrasonic excitation component is connected to a control circuit, and the ultrasonic excitation component comprises two or more ultrasonic excitation units, each ultrasonic excitation unit being connected to a corresponding probe to excite each probe, and the probes being used to emit ultrasonic waves.
