High-speed centrifuge is a routine laboratory centrifuge, widely used in research, education and production departments of biology, chemistry, medicine, etc. It is suitable for rapid synthesis of trace samples. The high-speed centrifuge has the characteristics of beautiful appearance, small size, light weight, automatic control of working time, simple operation and convenient use. Hunan Gilson Equipment Co., Ltd. mentioned that the high-speed refrigerated centrifuge mainly extracts the required components from the liquid mixture. According to the density of each substance, after adjusting the rotation, the dense liquid sinks to the bottom layer, and the liquid with low density floats. On top of that, layering the liquid will extract the pure material I need.
Some experts say that differential centrifugation is one of the most common methods. In this method, the centrifuge tube is full of uniform sample solution at the beginning of the fashion. After centrifugation at a certain speed for a certain period of time, two fractions, namely the precipitate and the supernatant, are obtained. However, the principle of differential centrifugation is that the operation is simple, but the purity of the separation is not high.
It is well known that the power supply problem of high speed centrifuges is the most difficult to handle. So, how do you deal with the power supply problem of high-speed centrifuges? Hunan Gilson Company summarized the following points:
First, the power failure is one of the reasons that cause the freezer to start and the cooling effect is poor. The same as the failure of the motor, the power supply and fuse should be checked separately.
Second, the voltage is too low, the safety device failure can also make the freezer unable to start, the voltage is too low may be the grid voltage is low, the distribution board wiring is too much, the power cord is too long. When the power line capacity is insufficient, not only the voltage is lowered, but also an accident may occur.
Third, the same is not the same. For example, if the high-speed centrifuge is installed in direct sunlight or poor ventilation, the radiator is not effective, or the radiator is covered with dust, which will also affect the cooling effect.
In addition, if the weight of the centrifuge tube is unbalanced, the placement is asymmetrical, or there is foreign matter in the rotor hole of the centrifuge, the effect of the high-speed centrifuge may be affected.
However, most of the above reasons are caused by incorrect operation. As long as the correct operation is performed, the abnormality may be eliminated. The most important point is that if there is any abnormality in the operation of the high-speed centrifuge, it must be stopped immediately and cannot be forced to run, otherwise the centrifuge may be damaged.
