Introduction Microwave power and its control: a real nonburst variable frequency microwave power stepless regulating function, dynamic and static setting, editing and saving according to the program in the range of 0-1300W. Features 1. Temperature and time control: time of microwave irradiation and stirring are freely set and changed; range of temperature control: 0-300°C (precision: ±1 °C) internally installed efficient cooling fan that accelerate the temperature reduction speed of reaction system; 2. Stirring mode: two modes of stirring: positive inversion mechanical stirring (0 to1000r/min) and magnetic stirring (0to200r/min), stirring speed is stepless adjustable. Two modes can carry on simultaneously or switch into another one according to the needs of action system. Stirring time, rotational speed and rotational mode can be change anytime by preset program or by hand. 3.Operation program: at least 100 experiment operation modes can be set, modified, saved and called. Each mode can set 10 operation steps. Parameters like reaction temperature and time of each step can be freely set and run by the program, control mode and various kinds of parameters can modified according to practical situation during operation. 4.Anticorrosive furnace chamber and chemical reactor: withdrawable anticorrosive scaleboard is installedthe useful space is 65L; tailormade high strength borosilicate glass, their volume can be 25 to 1500ml according to user’s needs (standard glass apparatus are reactors of 250ml, 500ml, 1000ml and drain sleeve); 5.Shield gas system: shield gas pipe that internally installed in temperature measurement bushing makes it more simple and convenient to install reactor; 6. Terminal display and control: a superlarge touch screen manmachine dialogue panel control. 7.The instrument replaces PID control algorithm with advanced FTC intelligent algorithm, which greatly improves regulation quality and makes screen display more striking, intuitionistic and diversified. All kinds of experiment parameters and working states (such as temperature, power and its change, stirring speed and mode of positive inversion, etc.) display on line in number or in different color and graph (columna, sector, colorful curve and so on), which is very clear; furthermore, the instrument also set a serialparallel interface that may communicate with the host, achieves a remote control and telemeter. Also, another computer control terminal can be equipped with according to the user’s need; Technical Parameter 1 Power source, 220V±10%, 50Hz; 2 Input Power, 1600W; 3 Microwave frequency, 2450MHz; 4 Size, 610mm*450mm*630mm; weight, 40Kg. 5 Simple work table and shield gas pipe*: completely internally installed mechanical stirring motor, poker bar, shield gas pipe and temperature measuring part, which makes the work table simpler and easier to operate. The mixing arm and its way of microwave shielding that is especially designed make the installing and taking out easier, which overcomes the phenomenon of microwave leakage that the present instruments often occur. 6 Combine shield gas pipe and temperature measurement bushing into one device, makes it more simple and convenient to install reactor. 7．Real variable frequency microwave: using a high frequency and high power resonant microwave power source, make the instrument has a real function of “nonburst variable frequency microwave power control and regulating”. 8 Superlarge furnace chamber: the furnace chamber’s volume is 65L, which is much larger than similar products at home and abroad, make the volume of the reaction vessel is optional (25to1500mL), putting in and taking out is more convenient. 9．Special design of stirring: two modes of stirring, mechanical stirring and magnetic stirring, are available to the instrument and a function of stepless adjustable positive inversion is established. 10 .The user can freely choose, set and switch those modes according to needs. 11.Advanced control unit: using the international certification high reliability control part, the mean time between failures(MTBF) up to 30000 hours; controlling by the super-large touch screen man-machine dialogue panel instead of keyboard, parameter setting and experiment operation is freely. 12. Unique data protection function: the experiment data and curve can real-time saved, which avoid data lose caused by power off. Equipping with host and spot printing functio, which convenient to save and analyze the experiment data. 13.Safety measures: dual safety door protection; internally installed withdrawable anticorrosive scaleboard which prevent the instrument from the damage caused by solution leakage or slopping. 14.Special design of poker bar makes the microwave leakage is less than 0.3mW/cm2 (national standard is 5 mW/cm2).
