SAFETY NOTICES
○ Mechanical Safety
WARNING：
Do not open the door while the rotor is spinning.
●
Do not attempt to slow or stop the spinning rotor by hand.
●
Do not incline or move the instrument while the rotor is spinning. Do not
●
place any object on the instrument or lean on the instrument.
Do not attempt to unlock the door forcefully while the rotor is spinning.
●
The centrifuge itself may move if the rotor fails during high-speed rotation.
●
Make sure there is a 30cm area around the centrifuge that will allow for such
movement and do not allow individuals to enter into that area during
operation. Also do not place dangerous objects such as flammable or
explosive materials on top of the centrifuge or in the surrounding area.
Do not remove the RLM adapter or optical adapter from the rotor, or replace
●
it with the adapter for another rotor. The adapter is a critical component that
detects the over-speed of the rotor: If an adapter that is not compatible with
the rotor is attached, the rotor could break, resulting in damage to the
ultracentrifuge.
The optical disk must match the maximum speed of the rotor, because the
●
optical disk is a critical component that detects the over-speed of the rotor: If
an optical disk that is not compatible with the rotor is attached, the rotor could
break, resulting in damage to the ultracentrifuge.
Use a RLM rotor manufactured by Hitachi Koki with only Hitachi ultracentrifuges.
●
Failure to do so can cause the centrifuge to become damaged.
Repairs, disassembly, and other modifications to the centrifuge are strictly prohibited
●
unless performed by a Hitachi Koki authorized sales/service representative.
Do not use the other's manufacturer's rotor without Hitachi Koki's permission.
●
Check the chemical resistance chart attached to the rotor, and do not use
●
any sample inapplicable to the rotor (including the buckets). Using such a
sample could corrode the rotor (including the buckets).
Do not exceed the allowable maximum rated speed of the rotor or buckets in use.
●
Do not use corroded, scratched or cracked rotor, buckets and assemblies.
●
Check that the rotor, buckets and assemblies are free of such abnormalities
before operation.
When using a swing rotor, check that the buckets are properly engaged with
●
the rotor pins before operation. Wrong setting can cause severe damage to
the instrument. Make sure that all the rotor buckets are of the same type.
If abnormal sound or vibration occurs, stop the operation immediately and
●
contact a Hitachi Koki authorized sales/service representative.
CAUTION：
Before using a rotor, be sure to read through the rotor instruction manual.
●
Check the chemical resistance chart attached to the rotor, and do not use any
●
sample inapplicable to the tubes, tube caps, bottles, or bottle caps, etc.
Using such a sample could corrode or deteriorate such parts and the sample
leakage might occur.
Use the rotor tubes and bottles within their actual capacities (see the
●
instruction manual).
Do not use tubes/bottles that have exceeded their life expectancy. Failure to
●
do so could result in damage of tubes/bottles and the rotor and the centrifuge.
The life expectancy of tubes/bottles depends on factors such as the
characteristics of samples, speed of the rotor used, and temperature.
Always check for deterioration and damage (cracks, deformation, and so on) on
tubes/bottles before using them. Do not use the tubes/ bottles if you find such a problem.
Mount the rotor onto the drive shaft gently and properly.
●
Do not drop the rotor or apply excessive force to the drive shaft to avoid
●
damage to the drive shaft.
