•
Unapproved rotors and associated accessories should not be used.
•
Before operating the instrument, check if the rotor and the rotor lid are
securely fastened.
•
The instrument should be operated with a rotor properly installed and secured
to the motor shaft.
•
Mount the rotor on the motor shaft properly, check it with spinning manually.
•
Do not stop the rotor by touching with hand during the instrument is running.
•
Emergency door open should be performed only when spinning is completely
stopped.
•
The rated speed or specific gravity should not be exceeded. Samples whose
density is greater than 1.2 g/ml must have reduced maximum rotational speed
to avoid rotor failure.
•
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.
•
ALWAYS load the tubes symmetrically with evenly weighted samples to avoid
rotor imbalance. If necessary, use the water blank to counterbalance the
unpaired sample.
•
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.
•
The rotors should be cleaned and kept dry after every use for longer life and
safety.
•
ALWAYS disconnect the power supply prior to maintenance care and service
to avoid electrical shock.
•
ALWAYS use proven disinfection procedures after centrifuging biohazardous
materials.
•
Flammable, toxic, radioactive, explosive, or corrosive materials should not be
centrifuged.
•
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.
Attention
•
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 in serious damage.
•
Install the instrument at a place without any kinds of corrosive gases.
