With the continuous development of the centrifuge industry, not only are the types of centrifuges gradually increasing, but the centrifugation methods of centrifuges are also constantly increasing. Below we will introduce several common onesContinuous wandering mind machineThe centrifugation method, I hope it can be helpful for everyone when choosing.
*Differential centrifugation method.
The so-called differential centrifugation method, experts from Jiayi Machinery Equipment Co., Ltd. told us, is to use different centrifugation speeds and times to separate particles with different settling speeds in batches. We know that when using the differential centrifugation method, the continuous flow centrifuge will gradually increase the centrifugation speed and alternate centrifugation. This way, at the bottom of the centrifuge tube of the continuous flow centrifuge, the largest and heaviest particles will be precipitated first, and the separated supernatant will undergo secondary separation while the centrifugation speed continues to increase. This will result in the second part of the larger and heavier particle "precipitate" and the "supernatant" containing small and light particles. By repeatedly operating and processing in this way, different particles in the liquid can be well separated.
Secondly, density gradient centrifugation method.
For the density gradient centrifugation method of continuous flow centrifuge, Jiayi Machinery Equipment Co., Ltd. believes that it can be understood as follows: when there is a difference in sedimentation coefficient between different particles, under a certain centrifugal force, the particles will settle at a certain speed and form zones in areas with different density gradients. The continuous flow machine using this method requires the preparation of a gradient mixer in advance to form a gradually increasing density gradient from the pipe mouth to the pipe bottom. Usually, this method is used for the separation of sucrose and glycerol.
Thirdly, equal density centrifugation method.
Perhaps some people believe that media of equal density cannot be separated in a continuous flow mechanism, but this is not the case. The equal density centrifugation method of continuous flow mechanism is that when there is a difference in buoyancy density between different particles, under the centrifugal force field, in a density gradient medium, the particles will continuously sink or float until they move to a position exactly equal to their respective densities, forming a zone, thereby separating substances with different buoyancy densities.
In summary, there are several common centrifugal methods for continuous flow of mind machines. Of course, there are far more methods of centrifugation than these, and with the continuous development of centrifugation technology, centrifugation methods will definitely gradually increase. It is essential to master the three commonly used methods for continuous flow thinking mentioned above, so that when encountering new methods, one can also integrate and master them more quickly.
