In recent years, some users have found that the centrifuge rotor will always be corroded when using the centrifuge. Seriously, the rotor will not be taken down, and the motor and the new rotor need to be replaced, thus affecting the service life of the centrifuge. Because domestic centrifuge manufacturers are made of alloy aluminum, alloy aluminum materials often contain copper, zinc, magnesium, etc., among which copper has the strongest strengthening effect and deteriorates corrosion resistance, so under the corrosion of many years, Seriously affected the service life of the rotor, Hunan Gilson Technology Development Co., Ltd. introduced a new type of composite material by collecting a large amount of data and referring to the new technology of foreign centrifuge rotors. It is ultra-light, high-strength, slow in heat conduction and most important. One point is the high resistance to corrosion, which greatly reduces the risk of replacing the new rotor due to corrosion.
Of course, most of the centrifuges used in the market still use aluminum alloy rotors. In order to prevent the corrosion phenomenon from continuing, we must do some protection. First of all, do not use the instrument in harmful gases or in humid environments. The rotor must be cleaned after use, removed from the shaft, and air-dried. If it is not taken for a long time, it will cause corrosion, and the sample filling volume and tightness of the centrifuge should be paid attention to during the use of the rotor. After use, be sure to put it on a special shelf. In order to increase the service life of the centrifuge, you must know some maintenance problems of the centrifuge in daily use.
1. When starting the centrifuge, the top cover of the centrifuge should be covered before it can be started slowly.
2. If the electric centrifuge is vibrating or the body is vibrating, the power should be cut off immediately to eliminate the fault immediately.
3. After the separation is finished, first close the centrifuge. After the centrifuge stops rotating, the centrifuge cover can be opened to take out the sample, and no external force can be used to force the movement to stop.
4, the centrifugation time is generally 1 to 2 minutes, during which the experimenter must not leave to do other things.
5. The bottom of the centrifuge casing should be padded with cotton or test tube pads.
