centrifuge.
Note：The button works only while the rotor stopped and the door is locked.

11
（1）Centrifuge
zIf the centrifuge is exposed to ultraviolet rays for a long time, the color of the door may be changed or
the label may be peel off. After using, cover the centrifuge with a piece of cloth to protect it from
direct exposure.
zIf the centrifuge needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent
solution.
zSterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.
（2）Rotor chamber
zIf the rotor needs cleaning, clean with cloth or sponge moistened with a neutral detergent solution.
Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.
（3）Drive shaft
zWe recommend regular maintenance for drive shaft. You can wipe the drive shaft with soft cloth, and
then apply a thin coat of silicon grease.
（4）Door
zClean and sterilize the door using the same method as the section（1）above.
（5）Rotor
zTo prevent corrosion, remove the rotor from rotor chamber. If not in use for a long term, then detach
the rotor lid and turn upside down to dry the tube holes and keep clean.
zFor sample leaks in the rotor, rinse the rotor with water. Apply a thin coat of silicon grease to the rotor
when it is completely dry.
zThe rotor should be checked every 3 months to ensure the tube and rotor holes keep are clean and
apply a thin coat of silicon grease.
CAUTION
zDo not directly pour water, neutral detergent or disinfectant solution into the rotor chamber, otherwise
fluids may leak into the drive units and cause corrosion or deterioration to the bearings.

Table 11.2 Cleaning and sterilizing conditions for tubes
11.2.2 Cleaning PC tubes
PC material is low in chemical resistance against alkaline solutions. Avoid using neutral detergents with
pH higher than 9. Note that pH of some neutral detergents are still higher than 9 even if diluted according
to the manufacturer’s instructions. Use detergent with its pH between 7 and 9.
11.2.3 Autoclaving PA、PC and PP tubes
PA begins softening at about 120 , PC and PP at about 130℃℃. Autoclave PA tubes at 115℃（0.7kg/cm2）
for 30 minutes, PC and PP tubes at 121℃（0.1kg/cm2）for 20 minutes. If a certain temperature is exceeded,
the tubes may be deformed.
When use a sterilizing chamber, please operate as follows:
(1) Place tubes in vertical position, mouths upward. If tubes are placed sideways, they may deform into an
oval shape due to gravity.
(2) Remove locking nut and lid to prevent from deformation or rupture.
(3) Wait until the sterilizing chamber cools down to the room temperature before removing tubes.

16
11.2.4 Conditions and life expectancy of tubes
The life expectancy of plastic tubes depends on the characteristics of samples, speed of the rotor used,
temperature applied and so on. When the plastic tubes are used for ordinary aqueous samples (pH between
5.0 and 9.0), their life expectancies are defined as follows.
Be operated at the maximum speed:
High quality tubes (PA、PC、PP): 30-50 operations
Ordinary tubes(PA、PC、PP): around 10 operations（Using in low speed can extend the tube life）.
Life expectancy of tubes also depends on the pretreatment conditions such as cleaning and sterilization,
lifetime can be cut down.
Notice: Do not use damaged or cracked tubes.
12. Calculate RCF
An RCF can be determined with the following calculation formula.
RCF=1.118×r×n2×10-5
r—rotating radius, unit: cm; n—rotating speed, unit: rpm
