Detailed Product Description: | Technical parameters of low-temperature ultrasonic extraction device ● ultra-low temperature ultrasonic extraction device technical parameters ● Ultrasonic power: 100 ~ 1500W continuously adjustable ● Ultrasonic Frequency: 25KHz ● Temperature range: -20 ~ 100 ℃ ● Reaction volume: 10 ~ 500ml ● ultrasonic probe diameter: Ф20mm ● Cold tank volume: 6L ● Compressor Power: 500W Main features of low-temperature ultrasonic extraction device Products by the ultrasonic wave generation systems, heating systems, cooling systems, temperature control system, mixing system components Magnetic stirring system can respond more fully, more uniform temperature Special three-neck reaction flask to meet a variety of test requirements (both into the various gases involved in the reaction, but also continuous feeding) Original European Taikang refrigeration compressor, cooling capacity, temperature uniformity Ultrasonic extraction of low-temperature instrument is the application of modern ultrasonic technology with low temperature system as a physical means of new chemical reaction device, mainly by the occurrence of high-power ultrasonic system, heating system, the compressor cooling system, temperature measurement temperature control systems, mixing systems and other components. Ultrasound refers to sound wave frequencies above 20000Hz. It can cause the transmission medium between the dramatic medium molecular friction and heat dissipation, resulting in a variety of primary and secondary effects of ultrasound, such as ultrasonic thermal effect, chemical effect of cavitation and other physical effects and so on. Because ultrasonic "cavitation" effect can cause changes in activity of reaction system to produce enough to trigger a chemical reaction of the instantaneous temperature and pressure, forms a local high-energy centers to promote the smooth progress of chemical reactions, which is catalyzed chemical reaction of ultrasonic factors. Secondary effects of ultrasound such as mechanical shock, emulsification, dispersion, crushing, etc. are conducive to the full range of mixing the reactants, than the general phase transfer catalysis, and mechanical agitation to promote more effective reaction to proceed smoothly, so the ultrasonic technology is gradually coming into chemical laboratory, as a means of physical catalyst, the reaction of organic chemistry appearance greatly changed. |
