Basic operation process:
1. Sample preparation: Firstly, it is necessary to prepare the sample to be extracted to ensure that it meets the experimental requirements.
2. Solvent selection: Choose a suitable solvent that can effectively extract the target component without causing damage to the instrument.
3. Preparation of ultrasonic equipment: Place the sample and solvent into the ultrasonic device, set the appropriate temperature and ultrasonic power.
4. Ultrasonic extraction: Turn on the ultrasonic equipment and perform ultrasonic extraction treatment. The oscillation of ultrasound can break the cell wall and promote the dissolution of target components into the solvent.
5. Filtration and Separation: After ultrasonic treatment is completed, simple filtration or centrifugation operations can be performed to separate solid particles from the solution.
6. Concentration and purification: Concentrate the solution to purify the target component.
7. Testing and analysis: Finally, the obtained extract is tested and analyzed to confirm the extraction effect.

Notes:
1. Safety first: During the operation, personal safety should be taken into account to avoid harm to the skin and body caused by ultrasound.
2. Experimental condition control: Control the experimental conditions such as ultrasonic power and temperature to ensure extraction efficiency and instrument stability.
3. Sample processing: The sample processing should be meticulous to avoid external contamination or damage to the sample.
4. Solvent selection: Choosing the appropriate solvent is crucial for the extraction effect and should be based on the properties of the target component.
5. Operation skills: Be patient and meticulous during operation to avoid operational errors that may affect the experimental results.
6. Instrument maintenance: Regularly maintain the ultrasonic equipment to ensure its normal operation.
7. Data recording: Timely record experimental data for subsequent analysis and summary.
8. Preparation before the experiment: Prepare all the reagents and equipment required for the experiment in advance to avoid affecting the progress of the experiment due to temporary preparation.
9. Strictly follow the operating procedures: Follow the laboratory operating procedures to ensure the safety and accuracy of the experiment.

10. Teamwork: During the experiment, it is important to work closely with team members, cooperate with each other, and complete the experimental tasks together.
