CW-2000 Ultrasonic-Microwave Cooperative Extraction / Reactor

The ultrasonic extraction instrument widely used in the laboratory currently transmits the ultrasonic waves generated by the ultrasonic transducer through the medium (usually water) and acts on the sample. This is an indirect mode of action. The extraction efficiency depends on the intensity of the vibration High and low, in order to solve the problem of low extraction efficiency, people often increase the extraction efficiency by increasing the power of the ultrasonic generator (³300W). However, the large ultrasonic power will make people feel uncomfortable.

The microwave-assisted extraction technology uses the target molecules in the sample to switch from the original thermal motion state to the microwave alternating electromagnetic field to quickly arrange the orientation under the action of the microwave electromagnetic field. The microwave energy is converted into the energy in the sample, thereby accelerating the target. The process of entering the solvent phase from the solid phase. Existing microwave-assisted extraction instruments include high-pressure closed-type and atmospheric-pressure open-type. Although each has its advantages, there are also some shortcomings. For example, the high-pressure microwave-assisted extraction instrument requires high strength and tightness of the extraction tank material, and the sample processing capacity is small (about 0.5-5g), which requires a long cooling time. The open-pressure microwave-assisted extraction instrument of atmospheric pressure overcomes the shortcomings of the high-pressure closed type to a certain extent, and the sample processing capacity is greatly increased, but the sample processing time is longer and the work efficiency is reduced.

In order to overcome the shortcomings of the above-mentioned single ultrasonic or microwave assisted technical methods, we try to combine ultrasonic and microwave energy organically, make full use of the ultrasonic vibration cavitation and the high energy effect of microwave, and first proposed to carry out under low temperature and pressure conditions. A new concept of microwave-ultrasonic synergy for sample pretreatment, and successfully developed the CW-2000 ultrasonic-microwave collaborative extraction / reaction instrument.

Performance characteristics

◎ Multipurpose for one machine: You can choose any one of the three modes of action : ultrasonic, microwave, or ultrasonic-microwave synergy. It can truly realize multipurpose for one machine. It is used to study chemical reactions, chemical synthesis, material preparation, and analysis of chemical samples. The best choice of methods and mechanisms;

Efficient ultrasonic vibration: The ultrasonic vibration energy directly acts on the sample container, which has high acoustic vibration efficiency, low energy consumption and low noise. The embedded wireless design makes it easier to place and remove the sample container;

Large sample capacity: the volume of the reactor can reach 500 mL, which greatly improves the sensitivity of the analysis; at the same time, containers of different shapes or volumes can be customized according to user needs;

Intuitive and convenient operation: The microwave power and action time can be adjusted arbitrarily, and the modes and degrees of ultrasonic and microwave action can be arbitrarily combined and set. Real-time monitoring of sample reaction status and reaction temperature;

Various power control modes: time control, temperature control and constant power control. It can be selected according to the sample system, work task and reaction type.

Low temperature and normal pressure environment: can reduce the damage to the organic structure of the sample;

Safe and reliable: Low temperature and normal pressure environment, no need to process or purchase special material sample container, operation is safer. Direct ultrasonic vibration has high efficiency and low noise; microwave leakage is less than 0.3 mW / cm 2 (national standard is 5 mW / cm 2 );

Wide range of applications: it can be widely used for sample preparation of inorganic, organic and biological analysis. In particular, it can be used as a new type of reactor, which is widely used in universities and scientific research units to carry out many meaningful research work in chemical reactions, organic synthesis, sample digestion or extraction methods;
