Is the centrifuge rotor related to vibration damping?

　　 Centrifuge Is the rotor related to shock absorption? Below, we’ll conduct a simple analysis using a medical centrifuge as an example.

　　The medical centrifuge is specially designed for hospitals, blood banks, radioimmunoassay laboratories, nuclear medicine facilities, and other similar institutions. It features automatic cap removal and centrifugation in a single step, completely resolving the longstanding challenge of removing caps from vacuum blood collection tubes in hospital settings. It is now a novel and highly efficient separation device.

　　The key difference between a medical centrifuge and a conventional centrifuge is that the medical centrifuge automatically removes the cap from vacuum blood collection tubes during the centrifugation process, thereby improving efficiency, enhancing user-friendliness, increasing intelligence, and boosting professionalism. By replacing manual cap removal, it prevents direct contact between reagents and the human body. Additionally, it avoids vibrations caused by cap removal, which could otherwise lead to redispersion of the blood and increase the risk of bacterial contamination.

　　The medical centrifuge features a brushless DC motor that requires no maintenance. It is microcomputer-controlled, allowing preselection of rotation speed, time, and centrifugal force, and comes with an LCD display for easy operation. It offers 10 different ramp-up and ramp-down rates, enabling rapid start-up and quick shutdown. The centrifuge is equipped with a built-in automatic balancing system, a stainless steel rotor chamber, and an integrated air shield. It also includes an electronic door lock, early-warning alarm function, and multiple safety protections, ensuring reliable and safe operation. Cleaning the centrifuge rotor is an essential part of daily maintenance. During rotor use, regular cleaning is necessary to prevent corrosion. If sample spills occur, immediately clean both the rotor and its accessories. Use plastic or wooden tools to remove and clean the O-rings or gaskets—never use metal tools to avoid scratching. Clean the rotor and its accessories with a neutral detergent and a soft brush. After washing the rotor with water, allow the rotor body or bucket to air-dry upside down. Regularly clean the O-rings or gaskets; it is recommended to replace them twice a year (or as needed based on specific requirements).

　　Storage and Maintenance of Medical Centrifuge Rotors

　　All fixed-angle rotors, vertical rotors, and near-vertical rotors should be stored upside down after removing the rotor cover/stopper. When storing horizontal rotors, the bucket should be removed. Rotors must be stored in a dry environment and should never be left inside the centrifuge. Regularly apply vacuum grease to the sealing rings and lubricant to the metal threads on the rotor cover and bucket lid.

　　Sterilization and Disinfection of Medical Centrifuge Rotors

　　The rotor and most rotor accessories (except those made of Noryl material) can be autoclaved at 121℃ for 1 hour. During autoclaving, remove the rotor lid, bucket lid, or rotor plug, and then invert the rotor/bucket for sterilization. 70% ethanol can be used for all rotor accessories; sodium hypochlorite can also be used, but it may cause discoloration of the rotor’s surface coating.

　　Vibration-damping structure: All centrifuges are equipped with a three-stage vibration-damping system to minimize vibrations at the source.

　　There are three sources of vibration in medical centrifuges:

　　(1) Vibration caused by the imbalance of the rotor itself

　　(2) Vibration caused by motor wind resistance

　　(3) Vibration of the motor itself.

　　Principle of vibration damping in medical centrifuges:

　　(1) Shock-absorbing springs absorb vibrations: atomic structure provides shock absorption.

　　(2) The vibration is transmitted from top to bottom to the baseplate, which absorbs the vibration due to its cast steel material and weight.

　　After reading the information above, do you now have a better understanding of the relationship between the centrifuge rotor and vibration damping?
