The XH-300UP Computerized Microwave-Ultrasonic-UV Combined Catalytic Synthesis System supplied by Guangzhou Jincheng Scientific Instrument Co., Ltd. features three modes: microwave, ultrasonic, and ultraviolet light, along with microwave hydrothermal functionality. It enables microwave hydrothermal reaction systems at different scales, representing a new generation of combined instruments that perfectly integrate electromagnetic waves, sound waves, and light waves.

The combined ultrasonic-UV catalytic synthesis system utilizes the thermal and non-thermal effects of microwaves to reduce molecular activation energy; employs the cavitation and mechanical effects of ultrasound to accelerate solute dissolution, with immense energy concentration during cavitation bubble collapse; and uses UV irradiation to cause internal electrons to undergo energy level transitions upon photon absorption, forming unstable excited states that further dissociate or undergo other reactions. Since absorption of photons at specific wavelengths is often characteristic of certain molecular groups, photocatalysis provides the optimal means to induce reactions at specific molecular sites. In summary, this instrument significantly accelerates chemical reaction rates through these physical and chemical processes, enabling reactions that do not occur under conventional conditions or enhancing existing reaction speeds and extents, thereby opening new reaction pathways.

Features:

The control system of the combined ultrasonic-UV catalytic synthesis system adopts the latest Android operating system, equipped with a quad-core 1.2GHz processor and 16GB storage. Combined with an 8-inch color LCD touch display, it allows real-time photography and video recording of the reaction process, which can be exported to a computer for data analysis. Parameters such as ultrasonic power and duty cycle, microwave power, temperature, pressure, and time can be set in stages. The ultrasonic transducer is enclosed and not exposed outside the instrument, nor can it be directly pulled out from the top of the chamber, avoiding safety hazards. Synergistic control technology, combined with constant temperature and constant power modes, maximizes the advantages of different energy fields such as microwave, ultrasonic, and UV, and systematically integrates them to deliver diverse effects in catalysis, organic/inorganic synthesis, natural product/mineral extraction, and nanomaterial preparation.
