UE-ML1000 Microwave Light Wave Ultrasonic Extractor

Description

At present, the widely used ultrasonic extractor in laboratory is to transfer the ultrasonic wave generated by the ultrasonic transducer through the medium (usually water) and act on the sample, which is an indirect mode of action. The extraction efficiency depends on the vibration intensity High and low, in order to solve the problem of low extraction efficiency.

Microwave-assisted extraction technology is the use of target molecules in the s ample under the action of microwave electromagnetic field, from the original state of thermal motion to follow the microwave alternating electromagnetic field and quickly arranged orientation, the microwave energy into the sample energy to accelerate the target The process of entering the solvent phase from the solid phase. The existing microwave-assisted extraction equipment, including high-pressure closed and atmospheric pressure open two, although each has its advantages, but there are some shortcomings. For example, high-pressure microwave-assisted extractives require very high strength and tightness of the extraction can material with small sample throughputs (about 0.5-5 g) and long cooling times. Atmospheric pressure open microwave assisted extraction to some extent to overcome the lack of high-pressure closed-end, sample handling capacity also increased significantly, but the sample processing time is longer, the work efficiency decreased.

In order to overcome the shortcomings of the above single ultrasonic or microwave assisted techniques and the charring phenomenon caused by the long time reaction of organic reactions, we try to combine the ultrasonic wave and the light wave (microwave) organically to make full use of the ultrasonic wave Vibration cavitation and high-energy effect of light waves (microwaves), the first concept of pre-processing of samples by synergistic light wave (microwave) -sult ultrasound under the conditions of low temperature and pressure was put forward. The successful development of the UE-ML1000 lightwave / Microwave / Ultrasound Combination Extraction System.
