First, the characteristics of low-speed refrigerated centrifuge:
1. Use microcomputer processor to control speed, temperature, time and LED digital display or liquid crystal display (LCD) (user optional).
2. The large torque brushless DC variable frequency motor is used, the starting torque is large, and the acceleration/deceleration time is short.
3. It has over-temperature, over-speed, electronic door locks, and other safety protection functions; it has a three-layer protective cover, which is safe and reliable, ensuring personal and machine safety.
4. Equipped with a variety of rotors, convenient for users to choose.
5. Imported fluorine-free compressor unit (refrigerant R404a) to meet environmental protection requirements.
6. For the separation and purification of radioimmunity, biochemistry, biopharmaceuticals, and blood products.
Second, the maintenance of low-speed refrigerated centrifuge:
1. For routine inspection and maintenance of circuit, electronic circuit and mechanical rotating parts, pay attention to whether the various indicators are damaged or aging, and regular maintenance is required.
2. Keep the centrifugal cup symmetrically balanced. If the sample tube placed in the centrifuge chamber is unbalanced, it will cause the centrifuge to shift. After the shutdown is reset, check if the instrument is normal.
3. Centrifuge cover bolts should be checked frequently to keep them flexible and prevent forced opening or closing. When an abnormality occurs, it is necessary to repair and replace it in time. Common faults, usually pay attention to observation, and promptly eliminate the solution.
4. Before use, please pay attention to check whether the rotor has corrosion points and fine cracks. The rotor that has been corroded or cracked is forbidden to use. If the rotor exceeds the shelf life, it should be checked frequently to ensure personal safety.
5. After centrifugation, dry the water in the centrifuge chamber and periodically apply a little neutral grease to the cone of the motor shaft. Remove the rotor from the centrifuge for a long time, wipe it clean and place it in a dry place.
6. Do a good job in the registration of the centrifuge working state and each working time, record the cause of the instrument failure and the troubleshooting method in time to ensure that the instrument works in the best condition.
