UH-IIDM 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, people often increase the extraction efficiency by increasing the ultrasonic generator power (≥300W). However, the larger ultrasonic power will cause unpleasant noise again.

Microwave-assisted extraction technology is the use of target molecules in the sample 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.

Features:

1. A multi-purpose machine: can choose any combination of microwave, ultrasonic, light wave, ultraviolet light and magnetic stirring to realize the multi-purpose of one machine; it is the most effective way to study chemical reaction, chemical synthesis, material preparation and pretreatment of chemical sample Good choice
