[0002] In soil testing, centrifugal analysis is often used to extract organic and inorganic components in the soil. For example, the centrifugal analysis method can be used to extract the content of nutrients such as heavy metals, ammonia nitrogen, and phosphate in the soil, and combined with other analytical methods to perform quantitative analysis. At the same time, centrifugal analysis can also be used to separate soil microorganisms, soil particles, etc., to conduct rapid and accurate analysis of soil microbial abundance and microbial community structure.
[0003] During use, the centrifugal analysis device needs to rotate at a high speed inside the centrifuge, which causes the device to shake greatly. However, most existing devices are not equipped with a buffer and shock-absorbing structure, which reduces the service life of the centrifugal analysis device. In addition, the centrifuge tube placement structure inside the centrifuge analysis device is mostly not adjustable, the clamping stability of the centrifuge tube is poor, and it is difficult to clamp centrifuge tubes of different diameters. It has certain limitations in use. Therefore, we propose a centrifugal analysis device for soil testing. Utility Model Content
