The principle of determining the separation speed and time of the centrifuge in the laboratory
The principle of determining the separation speed and time of the centrifuge in the laboratory:
1. Sample composition: Samples with small adhesion are easy to settle and separate, and samples with strong adhesion are not easy to settle and separate.
2. The difference in specific gravity of each component of the sample: the difference in specific gravity of each component of the sample is large, and it is easy to settle and separate. The difference in specific gravity of each component is small, and it is difficult to settle and separate.
3, particle size: large particles are easy to settle and separate, small particles are not easy to settle and separate.
4. Viscosity: The viscosity of the liquid in the sample is small, and it is easy to settle and separate. The viscosity of the liquid is large and it is not easy to settle and separate.
5. Separation requirements: high separation requirements, high separation speed and long separation time can be selected.
In general, the adhesion of the sample is small, the specific gravity difference of each component is large, the particles are large, the viscosity of the liquid is small, and the separation speed can be selected to be lower and the separation time is shorter. vice versa.
