Never operate the rotor beyond its rated speed.
Precautions for the use of desktop high-speed large-capacity centrifuge rotors:
1. It is forbidden to operate the rotor beyond its rated speed.
2. Unbalanced operation is strictly prohibited.
3. It is strictly forbidden to run without rotor at high speed.
4. It is strictly forbidden to touch the running rotor.
5, in the use and preservation of the rotor, should prevent bumps, scratches and scratches.
6. Regularly inspect the oxide layer on the inner and outer surfaces of the rotor. If there is peeling, corrosion, severe scratching, deformation or crack, stop using it.
7. When installing the rotor, wipe the center hole of the rotor chamber and the rotor with a clean soft cloth, and apply a thin layer of grease. Gently lift the rotor into the rotor seat of the centrifugal chamber with both hands, and screw the compression screw with the force rod. Press tight. After the rotor is pressed, the force rod must be pulled out and must not be operated randomly.
8. When using a horizontal rotor with a hood, do not let the hood bear heavy pressure to prevent the damper from deforming and causing the imbalance of the entire rotor. Pay special attention to the alignment of the upper and lower hoods to ensure the dynamic balance of the rotor and hood. There must be no foreign objects in the hood during operation.
9. When using the angle rotor, the rotor cover should be tightened.
10. When removing the horizontal rotor with the hood from the centrifugal chamber, first take out the upper hood cover, then take out the centrifuge tube, loosen the compression screw with the force rod, and then screw the T-shaped handle into the center hole of the rotor to lift the rotor. After loosening, you can pick up the rotor.
11. When removing the angle rotor from the centrifugal chamber, first unscrew the rotor cover, then take out the centrifuge tube, loosen the compression screw with the force rod, and then screw the rotor into the center hole of the rotor with the T-shaped handle to loosen the rotor. Can take out the rotor.
12. When taking the rotor, it is strictly forbidden to pull the rotor hard to avoid damage to the rotor seat.
13. After the separation is completed, wipe off the residual liquid on the inner and outer surfaces of the rotor and the centrifuge tube with a clean soft cloth, and dry it for use. Rotors and centrifuge tubes that are not in use should be taken out of the centrifuge chamber and stored in a clean and dry place. If the rotor is not used for a long time, it should be coated with a layer of paraffin.
14. In the use of the rotor, attention should be paid to the sample filling volume of the centrifuge tube and the tightness of the seal. The seal ring should be checked regularly for properness. If aging and damage occur, it should be replaced in time to avoid leakage. In the use of the rotor, leakage may occur due to damage, overfilling or poor sealing of the centrifuge tube. After the shutdown, the rotor is removed, cleaned in time, and sprayed with a protective agent.
15. If there is corrosive solvent in contact with the rotor, clean the rotor in time after shutdown, wipe and spray the protective agent.
16. When the average density of the separated samples is >1.2 g/mL, the rotor should be used at a reduced speed.
17. When using stainless steel centrifuge tubes, the rotor should be used at reduced speed.
18. The rotor is deactivated for three months and must be operated at a low speed for 10 minutes before it is allowed to operate at the maximum speed of the rotor.

Tape measure is a common measuring tool in daily life, and it is one of the necessary tools for families. Lu Ban ruler, Feng Shui ruler and Wen Gong ruler also belong to steel tape. Steel tape is a common tool in construction and decoration.
Steel tape can be divided into self winding tape, braking tape and rolling tape. Other names of steel tape are: steel tape, steel box ruler.
The second is the fiber tape measure, which is the tape measure that we often see. Many people say it's the cloth measure. The waist measure and the tailor measure all belong to this category. In the south of China and Hong Kong, it is often called tape measure or slide rule. Its material is PVC plastic and glass fiber, glass fiber can prevent the tape from being elongated in the process of using. Gift ruler is used for advertising and promotion. It is divided into steel tape (steel strip) and leather tape (PVC plastic fiber tape). It is usually cute and small.
