Ultrasonic pulverization equipment is used to pulverize animal and plant cells, bacteria, toothbrushes or tissues. Disperse rare earths and various inorganic mineral powders. It is an ideal device for accelerating the reaction speed of chemistry, biology and physics and accelerating the degassing of liquids. It can prepare nearly 100% of micron Large and small milk strands;
homogenize incompatible mixed liquids: polymerize some substances and precipitate other substances. Ultrasonic crushing equipment can achieve extraction, crushing, emulsification, homogenization, suspension, mutation, aerosol, crystallization and Prepare famous species under the electron microscope Various functions of the material sample. Ultrasound refers to electromagnetic waves with a frequency of about 20 kHz to 50 MHz. It is a mechanical wave that requires energy carriers and media to propagate. The alternating period of positive and negative pressure in the ultrasonic transmission process: in the positive phase, the medium molecules are squeezed to increase the original density of the medium; in the negative phase, the medium molecules are sparse and discrete, and the medium density decreases, that is, In other words, ultrasonic waves cannot polarize the molecules in the sample, but generate acoustic cavitation between the solvent and the sample, leading to the formation and growth of bubbles in the solution and the compression of smoke, thereby dispersing and increasing the solid sample.
The contact product between the sample and the extraction solvent increases the mass transfer rate of the Japanese standard substance from the solid phase to the liquid phase. In industrial applications, ultrasonic cleaning, drying, sterilization, atomization and non-destructive testing are one of This is a very mature and widely used technology. Ultra-Nanbo extract medicine is to add extraction medium (water, Z-cool or other organic falling agent) into the macro device, and crush or cut the Chinese medicinal materials into the extraction solvent as needed; the outer wall of the container is bonded and replaced Energy device vibrator or seal the vibrator in a stainless steel box and put it into the container:
turn on the ultrasonic generator, the vibrator emits ultrasonic waves into the extraction solvent, and the "cavitation effect" and mechanical action produced by the ultrasonic wave in the extraction solvent can effectively crush medicinal materials on the one hand The cell wall makes the active ingredients in a free state and falls into the extraction medium. On the other hand, it can accelerate the molecular movement of the extraction solvent, so that the extraction solvent and the active ingredients in the medicinal materials quickly contact, and are fused and mixed with each other. Cleaning and maintenance instructions for ultrasonic crushing equipment:
1. Disconnect the power before cleaning
2. Use a soft cloth at Hong Kong temperature to support the inner and outer surfaces of the ultrasonic cell disruptor; when the dirt is serious, you can wipe it off with a neutral detergent for washing utensils, and then wipe off the water stains with a clean soft cloth.
3. After each ultrasonic smashing of the sample, clean the horn probe with 20% ethanol and wipe it clean. Related notes:
1. It is strictly forbidden to turn on the horn when the horn is not inserted into the liquid (no load), otherwise it will damage the transducer or ultrasonic generator.
2. The amount of various cells, the length of time, and the size of the power are to be determined by the user according to various media, and the best value is selected.
3. After a certain period of time, the end of the horn will be corroded by cavitation and become hairy. It can be filed with oilstone or a fine file, otherwise it will affect the work effect.
4. The value displayed by the power meter is related to the voltage, the depth of the horn inserted into the liquid level and the load. The power supply voltage is lower than 220V, and the horn plunges into the liquid level suddenly, and the load concentration is too thick. The displayed value may be slightly smaller, and vice versa. High, this data is an analog parameter, and its size does not affect the actual power of ultrasonic emission.
5. During ultrasonic breaking, due to the cavitation effect of the ultra-south wave in the liquid, the temperature of the liquid will rise quickly. It is necessary to pay more attention to the proliferation of various cells. At the same time, an ice bath can be added for cooling.
