[0002] In the traditional experimental process, when conducting multiple sample experiments, it is usually necessary to oscillate the individual samples one by one, then let them stand for a period of time (strict timing is required), and then extract samples within a predetermined time range for testing. In order to ensure the accuracy and reliability of the data, the mutual interference between samples and the influence of external factors must be minimized. However, the traditional one-by-one operation method is difficult to meet the requirements of high efficiency and pollution-free, and is time-consuming and laborious. With the deepening of scientific research and the advancement of technology, the demand for being able to quickly process a large number of samples and maintain high precision is growing. Therefore, it is crucial to develop new experimental equipment and technologies to optimize the sample processing process.
