Operating the centrifuge after training is a responsible approach for both parties.

　　 Centrifuge It is essential to have professionally trained personnel operate the equipment. The differences between domestically produced and imported centrifuges are not significant—China has already mastered the core technologies of centrifuges. For high-speed centrifuges of comparable quality, price differences among models are relatively small; the main distinctions lie in their performance and configurations.

　　 Attention: Failure to comply with the relevant requirements and take appropriate measures could pose a potential risk of minor or moderate physical injury. Be aware of the danger of electric shock—even after the power has been disconnected, the rear end of the centrifuge may still carry dangerous voltages. To prevent children and the general public from coming into contact with or operating this equipment, ensure that it is used only for the purposes specified by the manufacturer. Unauthorized modifications or the use of spare parts not sold or recommended by the equipment manufacturer may result in electric shock and mechanical injuries.

　　 Tip: Please place the “Operating Instructions” in an easily accessible location near the centrifuge equipment, ensuring that all users can promptly read this manual. Warning: Proper transportation, storage, positioning, installation, as well as careful operation and maintenance are essential for the normal and safe operation of the centrifuge. During transportation and storage, ensure that the centrifuge is protected from physical impacts. Additionally, the instrument must be kept away from rain and should not be stored in environments with excessively high or low temperatures or high humidity levels. For specific operating instructions, please read the manual carefully.

　　 To ensure your personal safety, please read the user manual carefully before using this product and follow the instructions below:

　　1: Operation without a rotor is strictly prohibited;

2: It is strictly prohibited to operate the rotor beyond its rated speed.

3: It is strictly prohibited to operate with an imbalance exceeding 1 gram or to place test tubes asymmetrically.

4: It is strictly prohibited to open the centrifuge chamber door while the centrifuge is running.

5: It is strictly prohibited to touch the rotating rotor while it is in operation.

6: It is strictly prohibited to alter the parameters set on the frequency converter.

7: It is strictly prohibited to move the centrifuge while it is running.

8: The use of rotors or centrifuge tubes that are rusted or cracked is strictly prohibited.

9: The use of rotors beyond their service life is strictly prohibited.

　　Predicting failure by monitoring operational and physical indicators is a better approach. In centrifuges, the cover spring mechanism might loosen, bearings could wear out, and even with proper lubrication, the ear shaft might stop functioning. Any one of these issues is cause for concern, but taken together, they all point to impending failure.

　　If the centrifuge’s expected lifespan is regarded as the warranty period for optimal performance, the organization’s critical functions could be jeopardized. When a sudden, yet preventable failure occurs within the equipment’s expected lifespan, it can harm both revenue and operations.

　　In the life sciences or healthcare setting, such failures can adversely affect the structured development of research that could lead to disease treatments, or they can have negative consequences for someone’s health. Whenever a device malfunctions, repairs typically get it back up and running.

　　As equipment ages, it requires more frequent maintenance. Due to the shortage of spare parts, repairs will eventually become more expensive or even impossible, necessitating equipment replacement. On the other hand, if replacement is considered only after a permanent failure occurs, the new equipment might have to be reordered—otherwise, it won't be delivered and installed in time.

　　Finally, it’s worth noting that replacement of the centrifuge is an inevitable consequence of its aging; therefore, timely replacement is crucial!
