What Is An Ultrasonic Extractor? What Are Its Characteristics?
Feb 12, 2023
Ultrasonic extractor, also known as ultrasonic extractor, is mainly used to reduce the force between the target extract and the sample matrix through the rapid mechanical vibration wave generated by piezoelectric transducer to achieve solid-liquid extraction separation. In industrial application, ultrasonic wave is a very mature and widely used technology for cleaning, drying, sterilization, atomization and nondestructive testing. Because the ultrasonic extraction instrument does not need heating or the heating temperature is low, the extraction time is short, so the energy consumption is greatly reduced.
Application field:
1. Life science: the decomposition, fragmentation, extraction and extraction of DNA and protein in animal cells of bacteria, viruses, spores and other cellular structures, pruning of DNA/RNA/chromatin immunoprecipitation technology, such as the extraction of cell contents.
2. Material chemistry: dispersion, homogenization, emulsification, crushing and extraction of nanomaterials such as carbon nanotubes, graphene, titanium dioxide, silica, soil, etc.
3. Chinese herbal medicine: dispersion and extraction.
4. Accelerate chemical dissolution and chemical reaction. For example, it is used in chemical synthesis.
Features of ultrasonic extractor:
1. Only control system: LCD display, all data are clear at a glance;
2. Multiple working modes: continuous and pulse multiple modes, power can be adjusted at will;
3. Timing function: from 0-999 hours, settable;
4. On/off pulse timer: ensure high intensity processing of temperature-sensitive samples, and the on/off cycle can be set from 1 second to 99 minutes;
5. Automatic amplitude compensation: ensure that the probe amplitude does not change due to the load change during the ultrasonic process;
6. Dual safety protection: probe overload protection system;
7. Intelligent temperature control system: optional temperature probe;
8. Frequency compensation: automatically compensate the frequency according to the frequency.
