Safety Reminder
Common safety precautions
Carefully read the following safety precautions for a thorough understanding.
Follow the instructions and procedures described in this manual to operate this centrifuge safely.
Carefully read all safety messages in this manual and the safety instructions on the centrifuge.
Safety messages are labeled as indicated below. They are in combination with signal words of
“WARNING” and “CAUTION” with the safety alert symbol to call your attention to items or
operations that could be dangerous to you or other persons using this centrifuge. The definitions of
signal words are as follows:
WARNING：Personal Danger
Warning notes indicate any condition or practice, which if not strictly observed, could result in personal
injury or possible death.
CAUTION：Possible damage to centrifuge
Caution notes indicate any condition or practice, which if not strictly observed or remedied, could result in
damage or destruction of the centrifuge.
NOTE：Notes indicate an area or subject of special merit, emphasizing either the product’s capability or
common errors in operation or maintenance.
Do not operate the centrifuge in any manner not described in this User Manual. When in doubt or have
any troubles with this centrifuge,ASK FOR HELP.
The precautions described in this User Manual are carefully developed in an attempt to cover all the
possible risks. However, it is also important that you are alert for unexpected incidents. Be careful
operating this centrifuge.
WARNING
This centrifuge is not explosion-proof. Never use explosive or flammable samples.
Do not install the centrifuge in or near places where inflammable gases are generated or chemicals are
stored.

3
Do not place dangerous materials within 30cm of the centrifuge.
Prepare all necessary safety measures before using samples that are toxic, radioactive or contaminated
with pathogenic micro-organisms. Use of these is at your own responsibility.
If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic, radioactive
or pathogenic materials, clean it according to the decontamination procedure as specified.
If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then
notify the service center the details of the materials and procedure.
To avoid electrical shocks, insure hands are dry before handling the power cord or turning on/off the
power switch.
For safety purposes, do not enter within 30cm around this centrifuge when it is in operation.
While the rotor is rotating, never release the door lock.
Unauthorized repairs, disassembly, or modifying the centrifuge except by our service center are strictly
prohibited.
CAUTION
This centrifuge must be located on a firm and level table.
Make sure the centrifuge is horizontal before running.
Do not move or relocate the centrifuge when it is running.
If fluid spills in the rotor chamber, please promptly clean and dry with a dry cloth to avoid sample
contamination.
Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before
running the centrifuge.
Cautions with rotor
(1) Always check for corrosion and damage on the rotor surface before using it. Do not use the rotor
if an abnormality is found.
(2) Do not set the speed beyond the allowable minimum speed of the rotor kits (rotor and adapters).
Make sure to run it below the allowable maximum speed.
(3) Do not exceed the allowable imbalance.
(4) Use the rotor and tubes within their actual capacities.
If any abnormal condition occurs during operation, please stop it immediately and contact our
service center. Notify the service center is a warning code if displayed.

6. Rotor Preparation
6.1 Prepare the samples
6.2 Inject the samples into tubes
Do not exceed the actual capacity allowed in the user manual.
6.3 Keep the tubes balanced
Although the centrifuge can accept sample balancing by eye, we recommend that you keep this
centrifuge in a well-balanced condition to extend its life expectancy.
Never intentionally run the centrifuge under an unbalanced condition even though the allowable
imbalance is not exceeded.
6.4 Inspect the rotor
Check the rotor for corrosion or scratches before using.
CAUTION
If any abnormality such as scratches are found, stop using the rotor and contact our service center.
Only manufacturer’s rotors must be used with the unit.
6.5 Symmetrically load centrifuge tubes into rotor
CAUTION
Make sure the rotor is securely fixed on the shaft. Otherwise, the rotor may be moved off while
rotating and cause damage to the centrifuge and rotor.
CAUTION
Do not overload samples into the centrifuge which will cause leaking.

Table 10.2 Cleaning and sterilizing conditions for tubes
1) 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

13
to the manufacturer’s instructions. Use detergent with its pH between 7 and 9.
2) 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.
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.
