1-2. Safety Precautions
Before using the instrument, please read this operation manual to ensure correct usage through
understanding. Incorrect handling of the instrument could possibly result in personal injury or physical
damage on the instrument or its accessories.

7
Refrigerated, high-speed micro centrifuge 1730R
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 accessories.
Only use rotors from Gyrozen Co., Ltd. with appropriate centrifugal tubes and 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.

8
Refrigerated, high-speed micro centrifuge 1730R
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.

Should touch the [DOOR] button When the door is
closed (Door LED shows off)
Close the door until hearing clank shut.
When the door is opened, the door LED turns on.
The door is not opened while the instrument is running.
If the door is opened, the instrument could not be operated even with pressing the ‘Start’button.
For operational safety, this instrument has the automatic rotor recognition function.
When you supply the power, "Searching Rotor" /“Change to Rotor ID”will be appeared. If the rotor is
absent, the “Error 9”will be appeared. This message will be cleared after rotor coupling and running.
The door is not automatically opened after finishing operation to keep the sample at proper temperature.
Power Failure: If there is any power failure during operation, door is not opened with touching [Door]. Door
can be opened only when the operation is completely stopped and the power is on again. If you want to
open the door at the power failure, please refer to ‘4-9. Emergency Door Open’.
3-2. Rotor Coupling and Disassembling
Action
1. Before coupling a rotor, clean the motor shaft and chamber with soft dry
towel.
3-2-1. Fixed Angle Rotor/ PCR Rotor
2. Mount a proper rotor into the motor shaft.

11
Refrigerated, high-speed micro centrifuge 1730R
3. Grasp the rotor with one hand, and place Rotor Locking Tool
at the center hole of the rotor.
To assemble the rotor: Rotate the Rotor Locking Tool clockwise until
tightly assembled.
To disassemble the rotor: Rotate the Rotor Locking Tool
counterclockwise
4. To close of the rotor lid, rotate the rotor lid nut clockwise.
For opening lid: rotate the rotor lid nut counterclockwise.
When you run a fixed angle rotor, make sure that the rotor lid is tightly closed. If you don’t close
the rotor lid completely, it will be crushed.
☞
For operational safety, this instrument has the automatic rotor recognition function
When you supply the power, "Searching Rotor" /“Change to Rotor ID”will be appeared. If the rotor
is absent, the “Error 9”will be appeared. This message will be disappeared after rotor coupling.
3-3. Positioning of Sample Tubes
1. Before loading sample tubes, check the water drop or dirt in the rotor hole or inner adaptor.
If there is a water drop or dirt in the rotor hole or inner adaptor, remove it with soft dry
cloth.
2. Tubes should be placed in the rotor with same amount of samples at symmetrical positions.
Only use appropriate centrifugal tubes and do not exceed the speed beyond the tube’s
max g-force.
For safety, fill the sample for 70~80% in the tubes.
Correct Way of Sample Balancing & Tube Usage
☞If the number of samples is not in pair, please load the control tubes at each symmetrical position.
Otherwise, it results noise and vibration, which eventually damages the instrument.

12
Refrigerated, high-speed micro centrifuge 1730R

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 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.
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. 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

19
Refrigerated, high-speed micro centrifuge 1730R
to keep dry.
5-4. Rotor
1. If any parts are contaminated with samples, clean the rotor 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. If you do not use the instrument, keep the rotor separately 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.
