5Maintenance
5.1 Unit
1. Clean the outside the instrument with dry soft cloth. If necessary, dip the cloth in
neutral detergent and clean contaminated area. Keep completely dry after cleaning.
2. Do not use any volatile chemicals such as alcohol and benzene, etc.
3. Be careful not to make scratches on the surface of the instrument. The scratches can
cause corrosion on the surface of the instrument.
4. If any rust appears, clean it with neutral detergents and keep dry.
5.2 Chamber
1. Keep dry inside the chamber after every use.
2. If the chamber is contaminated, dip the cloth in neutral detergent and clean
contaminated area.
5.3 Motor shaft
1. Always make special attention to clean the motor shaft to avoid any imbalance
problem due to the contaminants.
2. After using the instrument, take out the rotor from the shaft, and clean the shaft with
dry soft cloth to keep dry.
5.4 Rotor
1. Corrosion and surface treatment of the rotor
a. Corrosion will occur if the acid or alkaline solution react to rotor. If the balance of
the rotor weight is not fit by the corrosion, it can cause severe vibration and noise
during high-speed rotation and result in damage to the drive shaft.
b. Rotor has a good corrosion resistance. But corrosion rate is related with humidity,
salt content and the amount of impurities in the atmosphere.

Personal Micro Centrifuge, mini
AS : 02-3452-8966/070-8620-5350/[e-mail] | 18
c. Against Carbonate, chromate, acetate and sulfide (etc.) such as neutral aqueous
solution, rotor has good corrosion resistance. But in the chloride solution,
corrosion resistance will be bad. In the oxidation solution, depending on the
increase of hydrogen ion concentration, the corrosion is increased. In the sulfate,
phosphoric etc., acid, erosion takes place quickly and eroded in particular regard
to hydrochloric acid.
2. Maintenance of rotor
a. Cleaning
If solution gets on the rotor that flows from the tube, immediately wipe it with a
soft cloth moistened with warm water. Be careful not to let the rotor surface
specially treated to flawless formation.
b. Dry
Please dry with caution places like narrow groove of the rotor. If using a hair dryer
to use in the home, it is more effective.
c. Storage
Keep the rotor in a clean, dry place. In particular, separate angle rotor with the lid
and turn over the body.
5.5 Movement of instrument
1. If you need to move or ship the instrument, be cautions to protect the motor shaft
from any physical impact or turbulence.
2. Do not mount a rotor in any cases of movement. Fill inside the chamber with proper
materials to keep the motor shaft on place and not to be influenced by physical
pressure.
