Introduction: YZ-1B low-temperature ultrasonic extraction instrument is a new type of chemical reaction device which uses modern ultrasonic technology combined with low temperature constant temperature system as the physical means. It is mainly composed of high-power ultrasonic system, heating system, compressor refrigeration system, temperature and temperature control system, mixing system And so on. Ultrasonic is the sound wave with a frequency higher than 20000 Hz. It spreads in the media can cause intense friction and heat dissipation between media molecules, resulting in various primary and secondary ultrasonic effects, such as ultrasonic thermal effects, chemical effects, cavitation effects and other physical effects. As the "cavitation" of ultrasonic can cause the change of the activity of the reaction system, the instantaneous high temperature and high pressure, which leads to the chemical reaction, can form the local high energy center and promote the smooth progress of the chemical reaction. This is the main factor of the ultrasonic catalytic chemical reaction. Ultrasonic effects such as mechanical shock, emulsification, diffusion, crushing and so on are conducive to the full range of reactants mixed, than the general phase transfer catalysis and mechanical mixing more effective to promote the smooth progress of the reaction, so ultrasonic technology has gradually entered Chemical laboratory, as a means of physical catalysis, so that the reaction of organic chemical chemistry greatly improved. Features: 1 products from the ultrasonic system, heating system, refrigeration system, temperature control system, stirring system components. 2 built-in magnetic stirring system can make the reaction more fully, the temperature is more uniform. 3 special multi - mouth reaction bottles to meet a variety of experimental requirements (both into the various gases can participate in the reaction, but also continuous feeding. 4 original Thai Taikang refrigeration compressor, cooling capacity, temperature uniformity. 5 reaction system can be fully sealed (domestic initiative). 6 ultrasonic horn immersion, the treatment effect is good. 7 working hours, ultrasonic intermittent can be set. 8 computer control, ultrasonic power continuously adjustable. 9 amplitude automatic adjustment, in different load conditions when the amplitude remains the same. 10 host controller for liquid crystal display.
