the key evaluation factors:
The physical state of the sample for ultrasonic extraction equipment:
Solid samples: For example, plant roots or ores, you need to select ultrasonic extraction equipment with an abrasion-resistant interior to avoid abrasive impurities.
Liquid samples: for oils and fats or liquid solutions, it is recommended to use stainless steel ultrasonic extraction equipment that are easy to clean and less susceptible to chemical reactions to prevent cross-contamination.
Viscous samples: such as biopolymer solutions, you need to choose a strong stirring ability of ultrasonic extraction equipment to ensure that the ultrasonic waves act evenly on the sample.
Chemical properties of the sample:
Volatile samples: When extracting volatile substances, the extraction tank with good sealing performance should be used to prevent the active ingredients from evaporating.
Reactive samples: If the sample contains substances that are easily reacted with metals, the use of ultrasonic extraction equipment made of metal should be avoided to avoid affecting the extraction effect.
Sensitive samples: For light-sensitive or temperature-sensitive samples, it is necessary to choose an ultrasonic extraction equipment that can be shaded and has a temperature control function to ensure that the extraction process is carried out under appropriate conditions.
Sample processing volume of ultrasonic extraction equipment:
Large Scale ultrasonic extraction equipment: For large scale processing, industrial grade extraction tanks with high capacity and power should be selected.
Laboratory scale ultrasonic extraction equipment: For small-scale research, it is more appropriate to choose a small volume, high-precision extraction tank to precisely control the experimental conditions.
By evaluating the above, you can ensure that the ultrasonic extraction equipment selected is suitable for the specific sample, thus improving extraction efficiency and sample integrity
