Ultrasonic pipettor

Abstract

The invention discloses an ultrasonic pipettor and relates to the field of micro / nano-manufacturing. The pipetting amount can be controlled to reach the nano-liter or picoliter specification. The ultrasonic pipettor disclosed by the invention comprises a vibration transfer component (1), a piezoelectric element (2), a microprobe (3), a pipetting ring (4) and an alternating current power supply (5), wherein the piezoelectric element (2) is arranged on the vibration transfer component (1), and the mounting surface is a radiating surface of the piezoelectric element (2); the tail end of the vibration transfer component (1) is connected with the microprobe (3); the pipetting ring (4) is arranged at the other end of the microprobe (3); and the driven piezoelectric element (2) is further connected with the alternating current power supply (5). With the adoption of the ultrasonic pipetting process, high pipetting precision of the cylindrical pipettor can be realized.

Description

technical field [0001] The invention relates to the field of micro-nano manufacturing, in particular to an ultrasonic pipette. Background technique [0002] Existing pipette is a kind of utensil for transferring liquid quantitatively, is widely used in fields such as biology, chemistry and clinical diagnostic laboratory, biotechnology laboratory, pharmacy and chemical laboratory, environmental laboratory, food laboratory A commonly used tool, the existing pipette specifications are generally above 0.1 microliters. Micro-nano technology has developed rapidly in recent years, and the specifications of reagents used in experiments are usually nanoliters or picoliters. However, due to the limitations of the pipetting principle, it is difficult for the existing pipettes to reach the specifications of nanoliters or picoliters. [0003] Therefore, the existing pipette specifications cannot meet the requirements of micro-nano experiments, and the volume of liquid taken is far grea...

Problems solved by technology

However, due to the limitation of the pipetting principle, the existing pipettes are difficult to reach the specifications of nanoliters or picoliters

[0003] Therefore, the existing pipette specifications cannot meet the requirements of micro-nano experiments, and the amount of liquid taken is far greater than the dose required for the experiment. In order to facilitate the experiment, a pipette with nanoliter and picoliter specifications is urgently needed
