4) Rotor
① Angle rotor (GRA-15-6A): GRA-15-6A is a basic rotor for 406 (MD406), and users can
insert 6 tubes to the rotor. The rotor can be easily inserted and removed from the main
body.
② Aluminum sleeve (GLB-15A-FA): Sleeves made of aluminum are inserted to a rotor and a
tube containing a blood sample is put into each sleeve. The maximum capacity of each
sleeve is 15㎖.
③ Adaptor: If users want to use tubes of which capacity is less than 15㎖, they will have to use
adaptors with sleeves. There are three types of adaptors for a GLB-15A-FA sleeve as
following.

▶ Installation
1) Installation place
① Install the machine at the solid and flat floor or table. If you place the centrifuge at the slope,
the axis of rotation is possibly changed because of the rotor weight.
② Install the machine about 30cm is departed from the wall because of the air circulation. If the
hole for the air circulation is blocked by anything, such as clothes or other devices, those
will make the air circulation impossible. Furthermore, if you install the device in a place with
lots of dusts, that will be cause the same problem. Therefore note that you should avoid
such place.
③ Install the machine at the place with appropriate temperature and humidity, because the
device is easily affected by temperature and humidity. It also has to be maintained with the
proper temperature & humidity.
④ Install the machine at the place without any kinds of corrosive gases. If the air surrounding
the device contains corrosive gases such as sulfurous acid gas or chlorine gas, that will
corrode rotors or any metal components of the device.
2) Supply the power
These centrifuges use 110V or 220V. Check proper voltage of your instrument and connect to
adequate power outlet. If the power input is more than ±10% of the recommended voltage or
fluctuating frequently, it may affect some functions of the instrument. It is advised to use AVR
(Automatic Voltage Regulator).

see the ‘RCF LED’ light start blinking. This
enables you to see the RCF value from
RPM/RCF display instead of RPM value.
② The conversion value from RPM to RCF is
calculated automatically(based on the maximum
radius and revolution). If you input the RCF
value, the RPM value will be calculated
automatically and changed.

▶ Maintenance (3) - Regular Inspection
1) Rotors and tube racks need to be cleaned regularly.
2) General checklist
- The spindle connector : This shall not be separated or bended.
- The spindle bearing : Check its rotating conditions. It shall rotate smoothly without any noises.
- The spring hinge : Check its tension.
- Rotor : Check if there is any scratch.
- Tube rack : Check if there is any scratch.
3) Speed
Measure the maximum rotation speed with a tachometer.
4) Time
Set the time 10 minutes and measure the time with a stop watch.
5) Imbalance sensor
If you run the device, in the imbalanced condition, the device shall be stopped an error
message with warning sound before achieving the maximum speed.
6) Door lock system
① The door shall not be opened and the LED light of the door shall be turned off when the
device is running. When you opened the door, the LED light of the door shall be turned on
and the device shall not be operated.
② Check if the door striker is worn out.

▶ Tube Arrangement
Each specimen shall be measured precisely before being put into each tube. Tube shall be
arranged symmetrically in the rotor. If the weight of each side is different, there will be severe
vibration, which can cause damages to a rotor and a shaft.
In case of a swing rotor, you should install all four buckets to the rotor before use.
▶ Blackout
If there is a blackout during operation, the door will not be opened. After blackout, if the rotor is
still running, the sensor will notice its rotation and the rotor will be decelerated rapidly with
warning sound.
