Other AbstractThe method involves collecting and storing a liquid image as a liquid template. A mechanical arm is controlled by a main control computer to hold a conical test tube. Images are captured by a camera in real-time manner to detect dual-phase liquid interface position and pipette tip position in the conical test tube. A liquid valve is started to start preset liquid transmission. Pipette shifting process is performed when the camera detects the two-phase liquid interface position in a tapered mouth of the conical test tube. Movement of the conical test tube is stopped by the mechanical arm. Two-phase liquid interface position is detected by the camera when distance between the two-phase liquid interface position and bottom position of the test tube is less than a preset value. The pipette valve is closed by main control computer for completing first-stage liquid-liquid extraction process. N-stage test tube liquid-liquid extraction process is completed.
