Product Description

The basic working principle of the table top centrifuge machine skilfully utilises the phenomenon of centrifugal force in physics to achieve effective layering and separation of substances of different densities through high-speed spinning action. When the centrifuge is activated, the rotor inside the centrifuge spins the sample rapidly, and the strong centrifugal force generated in the process becomes the key force for separating different components.

Under the action of centrifugal force, the components in the sample will be stratified according to their different densities. Specifically, the denser components are 'pushed' to the bottom of the centrifuge tube due to the stronger centrifugal force; on the other hand, the less dense components tend to stay in the upper or middle part of the liquid due to the relatively lower centrifugal force. This layering effect, based on density differences, allows for a clear separation of substances that would otherwise be mixed together.

It is important to note that the amount of centrifugal force is not arbitrary, but is determined by two key factors: the speed of the centrifuge and the radius of the rotor. A higher speed means that the sample undergoes more circular motions in the same amount of time, which generates a higher centrifugal force, while an increase in the radius of the rotor increases the radius of the circle in which the sample is rotating, which also enhances the effect of centrifugal force. Therefore, in actual operation, researchers can flexibly adjust the rotational speed and rotor radius of the centrifuge according to the characteristics of the substances to be separated and the target stratification effect, in order to achieve the best separation effect.

To sum up, through the centrifugal force generated by high-speed rotation, combined with the precise control of rotational speed and rotor radius, the table top centrifuge realises the effective layering and separation of substances with different densities, which provides a strong support for experiments and researches in the fields of scientific research, medical treatment, chemical industry and so on.
