Centrifuge Common Failure Analysis and Maintenance Methods

• Cleaning the Centrifuge

Clean the inner chamber and shell of the centrifuge at least once a week with a moist soft cloth, use water or a gentle neutral cleaner for cleaning, should not use alkaline solutions and other solvents that are abrasive to the centrifuge parts and materials. Use a rag or tweezers to move the stained material inside the centrifuge chamber. Wipe the centrifuge chamber with light movements to avoid damaging the temperature sensor inside the chamber.

• Checking the Balance

Check the balance of the centrifuge spindle system every 3 months. Regularly check whether the machine is level by placing a level meter on the centrifuge spindle or centrifuge body, and if it is found that it is not level, it must be adjusted to the level state.

• Adjusting the Level

The centrifuge needs to re-adjust the level of the instrument if it is moved to a different placement.

• Verifying Rotational Speed

Check whether the rotational speed matches the value shown on the screen every 3 months.

• Weekly Boot and Function Test

Once a week to boot, put a rotor in the low-speed state running, and check to ensure that the centrifuge can work properly.

• Checking for Cracked Centrifuge Tubes

Use should check whether the centrifugal tube is cracked, for any cracked centrifugal tube, do not use it, the centrifugation process, such as centrifugal tube rupture, will cause greater vibration, and should be immediately shut down to deal with.

• Inspecting the Rotor

Each time before use should check the rotor for corrosion points and minor cracks, prohibit the use of corroded or cracked rotor.

• Avoiding Overuse of the Rotor

Prohibit the use of more than the rated life of the rotor, to avoid the risk of rotor flying crack.

• Proper Rotor Maintenance and Storage

After centrifugation, the rotor should be removed from the centrifugal chamber, cleaned and wiped dry promptly with neutral detergent to prevent chemical corrosion, and stored upside down in a dry and ventilated place. It is not allowed to scrub the rotor with phi neutral detergent, and it is not allowed to dry the rotor with electric hot air. The center hole of the rotor should be coated with a little grease or medical Vaseline protection to avoid corrosion affecting the service life of the rotor. The centrifuge should open the top cover when it is not applicable for a short time to keep the centrifugal chamber dry.

• Safety Precautions during Maintenance

The instrument is not applicable for a long time or maintenance should be removed from the main power plug, otherwise, the instrument will be electrified, especially since maintenance is prone to safety accidents.

• Proper Rotor Storage

The rotor should be removed from the centrifugal chamber when not in use, and cannot be stored in the centrifugal chamber.
