Ultrasonic extractorIt is mainly based on the principle of ultrasonic action. The rapid mechanical vibration wave generated by the piezoelectric transducer acts on the cell wall (cell membrane) of the material being fed. The powerful mechanical wave can destroy the cell wall of plant cells (cell membrane of animal cells), so that the internal solutes in cells can be quickly dissolved into the extraction solvent, and then the extract is obtained through filtration, centrifugation, ethanol precipitation, concentration, spray drying and other processes.
Ultrasonic extractorOperation method: Add an appropriate amount of water as a conductive medium to the extraction container, crush the sample, weigh it, and depending on its properties, some may need to be soaked in an extraction agent. Place the container into the slot of the extraction container, turn on the ultrasonic generator, sonicate for a certain period of time according to the set conditions, stop sonication, and cool to room temperature. Continuous ultrasound extraction is also a highly efficient extraction method that can be used for various analytical purposes.
Due to its low extraction temperature, high extraction rate, and short extraction time, ultrasonic extraction is particularly advantageous for the extraction of natural products and bioactive components. Ultrasonic extraction has broad application prospects not only in industry. It has become an important means of sample pretreatment in analysis.
