Centrifugal Principle
When the suspension containing fine particles stands still, the suspended particles gradually sink due to the action of the gravity field. The heavier the particles, the faster they sink, whereas particles with a density less than the liquid will float. The speed at which particles move under a gravity field is related to the size, shape and density of the particles, and is also related to the strength of the gravity field and the viscosity of the liquid. Particles the size of red blood cells, several micrometers in diameter, can be observed settling under normal gravity. In addition, diffusion occurs when substances settle in the medium. Diffusion is unconditional and absolute. Diffusion is inversely proportional to the mass of the substance. The smaller the particles, the more severe the diffusion. Subsidence is relative and conditional, and requires external force to move. Settlement is proportional to the weight of the object. The larger the particles, the faster they settle. For particles smaller than a few microns, such as viruses or proteins, they form a colloid or semi-colloidal state in solution, and it is impossible to observe the sedimentation process using gravity alone. Because the smaller the particles, the slower they settle and the more serious the diffusion phenomenon. Therefore, it is necessary to use a centrifuge to generate strong centrifugal force to force these particles to overcome diffusion and produce sedimentation motion.

Daily maintenance
Before running the centrifuge, you should cut off the power and release the centrifuge brake. You can try rotating the drum by hand to see if there is any bite. Condition.
Check whether there are any looseness or abnormalities in other parts.
Plug in the power and drive clockwise. It usually takes about seconds to go from standstill to normal operation.
Usually, each piece of equipment must be run empty for about an hour after arriving at the factory, and it can work without any abnormality.
Materials should be placed as evenly as possible.
Must be operated by dedicated personnel, and the capacity must not exceed the rated capacity.
It is strictly forbidden to overspeed the machine to avoid affecting the service life of the machine.
After the machine is started, if there is any abnormality, it must be stopped for inspection. If necessary, it must be disassembled, cleaned and repaired.
The centrifuge operates at high speed, so you must not touch the drum with your body to prevent accidents.
To ensure the normal operation of the centrifuge, the rotating parts should be refueled and maintained every month. At the same time, check the running lubrication condition of the bearing, whether there is any wear and tear, whether the components in the brake device are worn, and if it is serious, replace the bearing cap to see if there is any oil leakage.

Usage precautions
At present, electric centrifuges are commonly used in laboratories. Electric centrifuges rotate quickly. Pay attention to safety, especially to prevent the centrifuge from running. During this period, due to imbalance or aging of the test tube pad, the centrifuge moved while working and fell off the experimental table in unison, or because the lid was not covered and the centrifuge tube broke due to vibration, the glass fragments flew out, causing accidents. Therefore, when using a centrifuge, you must pay attention to the following operations.
The bottom of the centrifuge casing should be padded with cotton or a test tube pad.
If the electric centrifuge makes noise or the body vibrates, the power supply should be cut off immediately and the fault should be eliminated immediately.
The centrifuge tubes must be placed symmetrically into the casing to prevent the body from vibrating. If there is only one sample tube, the other one must be replaced with water of equal mass.
When starting the centrifuge, the top cover of the centrifuge should be closed before starting slowly.
