Problems solved by technology

[0004] It usually takes more than 30 minutes from the sample centrifuge tube vibration extraction to the centrifugal layering purification process. The whole process needs to be manually waited to avoid the centrifuge tube falling off during the vibration, and the operation of the oscillator or shaker is cumbersome, and the volume is too large to waste laboratory work. Therefore, it is urgent to invent a device to solve this problem

Description

technical field [0001] The invention relates to a centrifuge, in particular to a centrifugal vibration integrated machine. Background technique [0002] A centrifuge is a device that separates a liquid-phase heterogeneous system by centrifugal force. According to the difference in sedimentation coefficient, mass, density, etc. of substances, the method of separating, concentrating and purifying substances by applying strong centrifugal force is called centrifugation, which is widely used in physical and chemical testing laboratories. [0003] In the process of rapid detection of pesticides in fruits and vegetables and veterinary drugs in food of animal origin, the samples are weighed and put into centrifuge tubes during the pretreatment process, adding salt (sodium chloride or magnesium chloride) and extracting solution (acetonitrile or dichloromethane) Finally, it usually needs to be fully shaken for 20-30 minutes to extract the substance in the sample. However, this proc...
