1.2 Safety Precautions
Before using the instrument, please read this operation manual to ensure correct usage.
Incorrect handling of the instrument could possibly result in personal injury or physical
damage on the instrument or its accessories.
1. ALWAYS locate the instrument on a flat, rigid and stable table capable of withstanding
the weight of the instrument and its spinning operation.
2. ALWAYS make a safety zone of 30 cm around the centrifuge to indicate that neither
hazardous materials nor persons should be permitted within the area during operation.
ALWAYS position the instrument with enough space on each side of instrument to
ensure proper air circulation.
3. ALWAYS install the instrument within a temperature and humidity controlled environment.
(Permissible ambient temperature: +5°C ~ +35 °C, Relative humidity: ≤ 85%)
4. Before connecting the power, check the rated voltage.
5. Should not use unapproved rotors and associated accessories.
Only use rotors from Gyrozen Co., Ltd. with appropriate centrifugal tubes and

4
MicroCentrifuge, mini
suitable adaptors to embrace sample containers tightly enough inside rotors.
6. Before operating the instrument, check if the rotor and the rotor lid are securely fastened.
Should operate the instrument with a rotor properly installed and secured to the
motor shaft.
7. Mount the rotor on the motor shaft properly, check it with spinning manually.
8. Do not stop the rotor by touching with hand during the instrument is running.
9. Emergency door open should be performed only when spinning is completely stopped.
10. Should not exceed the rated speed or specific gravity. Samples whose density is greater
than 1.2g/ml must have reduced maximum rotational speed to avoid rotor failure.
11. The sample content should not exceed 80% of total capacity of a tube. Otherwise, it
would cause spillage of sample fluid and even the tube breakage.
12. ALWAYS load the tubes symmetrically with evenly weighted samples to avoid rotor
imbalance. If necessary, use the water blank to counterbalance the unpaired sample.
13. The operation speed should not exceed the highest value of the individual guaranteed g-
forces of each centrifuge, rotor, bucket or adaptors and sample container, especially the
guaranteed g-force of sample container should not be neglected.
14. The rotors should be cleaned and kept dry after every use for longer life and safety.
15. ALWAYS disconnect the power supply prior to maintenance care and service to avoid
electrical shock.
16. ALWAYS use proven disinfection procedures after centrifuging biohazardous materials.
17. Should not centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.
18. When it is necessary to use toxic or radioactive materials or pathogenic micro-organisms
which belong to the Risk Group II of WHO: “Laboratory Bio- safety Manual,” should
follow national regulations.
Do not place dangerous materials within 30 cm distance around the instrument, and that is also
recommended by IEC 61010-2-020.
Use the emergency door open function only when the door button on the control panel is dumb
under the condition of complete stop of rotor running.
Never try to open or move the instrument if it is not completely stopped.
If the power input is more than +/- 10% of the recommended voltage or fluctuates frequently, it may
cause malfunction of the instrument and often result serious damage.
Install the instrument at the place without any kinds of corrosive gases.

Note!
When the PCR rotor is coupled, please do not speed over 6,000 rpm/2,400 rcf.
3.2 Rotor Coupling and Disassembling
3.2.1 Fixed Angle Rotor
Action
1
Before coupling a rotor, clean the
motor shaft, rotor, and chamber with
soft dry towel.
▶If you find any foreign substances,
they must be removed from the motor
shaft, rotor and chamber.
2
Mount a proper rotor into the motor
shaft and fix it using Rotor Locking Nut.
▶To assemble the rotor, rotate the
Rotor Locking Nut clockwise until
tightly assembled.
▶To disassemble the rotor, rotate the
Rotor Locking Nut counterclockwise.
▶Grasp the rotor with one hand and
assemble or disassemble the rotor
using the Rotor Locking Nut.

3.3 Positioning of Sample Tubes
Action
1
2
Before loading sample tubes, check the water
drop or dirt in the rotor hole or inner adaptor.
▶If you find any water drops or dirt in the
rotor hole or adaptor, remove them with soft
and dry cloth.
The sample tubes should be placed in the rotor
holes in a balanced way.
▶The sample tubes should be loaded
symmetrically with the density and the weight
considered to avoid imbalance.
▶In case the number of samples cannot make
balance in weight, please use control tubes.
Otherwise, it can cause noise or vibration, which
may damage the instrument.
▶Only use appropriate centrifugal tubes and
do not exceed the speed beyond the tube’s max
g-strength.
▶If the sample contents exceed 80% of total
capacity of the tube, it may cause spillage of the
sample and the tube breakage. For safety, fill
the 70~80% of the tube volume at the
maximum.

5. Maintenance
5.1 Outer part of Instrument
1. Clean the outside of the instrument with dry soft cloth. If necessary, dip the cloth in
neutral detergent and clean any contaminated area. Keep completely dry after cleaning.
2. Do not use any volatile chemicals such as alcohol, benzene, benzole, and thinner, etc.
3. Be careful not to make scratches on the surface of the instrument.
Scratches may cause corrosion on the surface of the instrument.
Any parts with rust should be cleaned with neutral detergents and kept dry.
5.2 Chamber
1. Keep dry inside the chamber after every use.
2. If the chamber is contaminated, clean contaminated area with the cloth dipped in
neutral detergent.
5.3 Shaft
1. Always keep the motor shaft clean to avoid any imbalance problem caused by 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.
3. If the rotor cannot be easily removed from the shaft, do not pull the rotor by force and
call a service engineer authorized by GYROZEN Co., Ltd.
5.4 Rotor
1. If any parts become contaminated, clean them with soft wet cloth and keep the rotor
dry.
2. Be careful not to make scratches inside or on the surface of rotors. Any small scratches
can cause corrosion of the rotor and big damage to the instrument.
3. While the instrument is not used, remove the rotor from the motor shaft and stand it
upside down.
5.5 Transportation of Instrument
1. If you need to move or ship the instrument, be cautious 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.
