Description

Technical Field

[0002] Microorganisms are a class of primitive, low-level, and tiny organisms, including bacteria, viruses, fungi, etc. Microorganisms in nature often coexist in a mixed manner. However, in biopharmaceuticals, medical testing, and scientific research, strains containing only one type of microorganism are generally required. Therefore, the microorganisms need to be separated and purified. The separation and purification of microbial strains mostly uses centrifugation. The rotor of the microbial separation device drives the centrifuge tube to rotate at high speed. Under the action of centrifugal force, microorganisms with different sedimentation coefficients and buoyancy densities in the sample are separated.

[0003] During the separation and purification process of microbial strains, the centrifugal test tube needs to have a certain centrifugal angle. The centrifugal angle is the angle between the length direction of the test tube and the gravity direction. The centrifugal angle not only affects the magnitude and direction of the centrifugal force, but also affects the separation effect and the working stability of the equipment. A suitable centrifugal angle needs to be selected for different reagent samples. The centrifugal angle of the microbial separation and purification device used in daily life is often fixed. If the centrifugal angle needs to be adjusted, the entire rotor must be disassembled and replaced, which affects the working efficiency of the microbial separation and purification. Therefore, the utility model proposes a device for rapid separation and purification of microbial strains. Utility Model Content
