6.1.3 maintenance
6.1.3.1
Do not use sharp objects to collide with the rotor. During transportation and
disassembly, it is necessary to prevent collisions and prevent cracks in the rotor during
use due to scratches or external injuries.
6.1.3.2
Regularly inspect the rotor components (especially the bottom of the test tube
hole) for corrosion spots, grooves, and small cracks. If any of the above conditions are
found, please stop using the rotor and contact our company.
When disassembling the rotor, grab it with both hands and lift it
vertically, do not shake it left or right!
6.1.3.3
Normally, the rotor is cleaned once a week. If separating salt solutions or other
corrosive samples, please clean them immediately after use. If the sample is found
splashing, soaking, or dripping on the rotor during use, it should be immediately
sucked dry and locally cleaned.
6.1.3.4
When cleaning the rotor, please use neutral detergent to wet sponge or cotton
cloth, and then use distilled water to wash the detergent. Do not sprinkle or spray the
rotor with water, as the liquid may be carried away and cause corrosion. Allow to dry
upside down after cleaning.
6.1.3.5
Use a cloth or tweezers to remove debris from the centrifuge chamber.
6.1.3.6
