Don't use the rotor overload, or it will cause explosion of the rotor and the
debris will damage the centrifuge.
4.7 Filling of sample in the centrifuge
Please carefully examine that whether the centrifuge container using (centrifuge tubes, etc.) is consistent
with its rated maximum allowed acceleration (centrifugal force), if possible, please lower the speed. When
the centrifuge is running, if the balance performance is better, the separated area of the separating samples
won't interface with each other because of the vibration, and then the effect of centrifuge will be better.
Please try to keep balance when filling centrifuge with samples to get good effect of balance during running.
Choose proper container for placing samples please.
Please note the using life of the centrifugal container. Check whether the
centrifugal container (plastic, glass) is damaged or not when it's under
maximum allowed load and maximum allowed speed. If there's anything damaged,
please replace in time.
4.8 Use the rotor in safe way
4.8.1 Fill samples and place the test-tubes exactly and symmetrically before the running of rotor.
4.8.2 Angle rotor shouldn't run in the critical speed area of 800r/min for long time, otherwise the big vibration
caused by the machine will impact using life.
4.8.3 When replacing rotors, loose the locknut anti-clockwise with the wrench attached, and then you can
replace rotor.
Don't start the machine before the screw is tighten on the shaft.
4.8.5 If you need use the centrifuge repeatedly, please check whether the rotor locknut loose or not after
several times. If the locknut is loose, you must tighten the screw and then start the machine
4.8.6 The centrifuge tubes can load the samples at different time but it must be symmetric loading of
samples (the weight of error allowed ≤ 1.5g). Start the machine with asymmetric loading is not allowed!
4. 9 Example of operating of parameter setting
4.9.1 The operation is as following if the rotor is No. 1: power on→switch on the right side of the device, and
at this time the control panel will light on.
Setting the parameters as following:
4.9.2 Press the setting knob vertically on the control panel→ make the number flash on the ROTOR
→rotate the setting knob to set the rotor number 0001.
If you need set the parameters continuously, after finishing the last
parameters setting, you can continue press the setting knob vertically to set
next one until finish all the parameters setting. And then it will flash for 3
times automatically. That's sign of conferment of the parameters setting. No need do
that manually.
4.9.3 Setting of speed: Press the setting knob vertically on the control panel→make the number flash on the
SPEED →rotate the setting knob to set the speed 4000.
