Low temperature ultrasonic extractor temperature is more uniform and full response
Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand low-temperature ultrasonic extraction instrument, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more guaranteed and affordable. The low-temperature ultrasonic extraction instrument is a new type of chemical reaction device that uses modern ultrasonic technology combined with a low-temperature constant temperature system as a physical means. It is mainly composed of a high-power ultrasonic generation system, heating system, compressor refrigeration system, and temperature measurement and temperature control. System, mixing system, etc. Ultrasound refers to sound waves with a frequency higher than 20,000 Hz. Its propagation in the medium can cause violent friction and heat dissipation between the molecules of the medium, thereby generating various primary and secondary ultrasonic effects, such as ultrasonic thermal effects, chemical effects, cavitation effects, and other physical effects. Because of the "cavitation" effect of ultrasonic waves, the activity of the reaction system can be changed, generating instantaneous high temperature and pressure sufficient to initiate chemical reactions, forming local high-energy centers, and promoting the smooth progress of chemical reactions. This is the main factor for ultrasonic catalytic chemical reactions. Ultrasonic secondary effects such as mechanical shock, emulsification, diffusion, crushing, etc. are conducive to the full mixing of the reactants, which is more effective than general phase transfer catalysis and mechanical stirring to promote the smooth progress of the reaction, so ultrasonic technology has gradually entered The chemical laboratory, as a physical catalysis method, has greatly improved the appearance of organic drug chemistry.
