7. Maintenance
7.1 Maintenance after operation
(1) Centrifuge
If the centrifuge is heavily stained, clean it with a cloth or sponge moistened with a
dilute solution of neutral detergent. Sterilize the centrifuge by wiping with a cloth
moistened with 70% ethanol solution.
(2) Rotor chamber
■ Wipe frost or moisture in the rotor chamber with a soft cloth to prevent getting in the
sample or corrosion. If the rotor chamber is dirty, clean with a cloth or sponge
moistened with a neutral detergent solution. Sterilize the centrifuge by wiping with a
cloth moistened with 70% ethanol solution.
■ When the tubes are broken, remove the rotor and then clean the bottom of the rotor
chamber, because there might be the fragments of the tubes or the sample on the
bottom of the rotor chamber.
(3) Drive shaft
Wipe the drive shaft with a soft cloth if the surface is dirty.
To prevent scuffing of the rotor, apply a thin coat of lubricant for screws to the drive
shaft once a month (purchase the lubricant for screw (Part No. 84810601) separately).
(4) Door
■ Clean and sterilize the door in the same manner as specified in the step (1).
■ The door packing may have been deformed if air leaks through the door or the door
rattles. Contact a Dynamica authorized sales/service representative for an
inspection.
(5) Rotor
For more details, refer to the rotor instruction manual.
CAUTION
：
●
If the centrifuge is exposed to ultraviolet rays for a long time, the color of the covers
may be changed or the coating may be peeled off. After use, cover the centrifuge
with a cloth to protect it from direct exposure.
●
Do not sprinkle water, neutral detergent or disinfectant solution directly on the
centrifuge. Otherwise fluids might leak into the inside of the centrifuge from the door
hook hole and it might cause corrosion or deterioration of the centrifuge.
CAUTION
：
● Do not expose the rotor chamber to acids, salts, etc. Use of these materials can cause
a chemical reaction that initiates corrosion such as rust. When samples contain these
materials, remove the rotor from the centrifuge after the operation and clean the rotor
chamber thoroughly.
● Do not pour water, neutral detergent or disinfectant solution directly into the rotor
chamber. Otherwise fluids may leak into the inside of the centrifuge and cause
corrosion or deterioration of the centrifuge.
