Centrifuge operation precautions 1. When the centrifuge is in the pre-cooling state, the centrifuge cover must be closed. After the centrifuge is finished, the rotor should be placed on the test bench and the residual water in the chamber should be dried. The centrifuge cover is open. Anqiu Ginger is famous for its bright yellow skin, good fruity shape, compact structure and strong ginger flavor. In addition to containing a large number of carbohydrates, proteins, vitamins and minerals, it also contains a large number of gingerol, gingerolone, gingerol and gingerol, etc., which has high edible value and medicinal value.

2. When the rotor is pre-cooled, the rotor cover can be placed on the platform of the centrifuge or placed on the test bench. Do not screw it on the rotor, because the rotor cover will be activated if it is accidentally activated. Will fly out, causing an accident!
3. After the screw cap is tightened, be sure to touch the gap between the rotor and the cover with your fingers. If there is a gap, unscrew and retighten until the gap is confirmed to start the centrifuge.
4. During the centrifugation process, the operator must not leave the centrifuge chamber. In the event of an abnormal situation, the operator cannot turn off the power supply.) Press STOP. Fill in the centrifuge usage record before pre-cooling.
5. Do not use fake centrifuge tubes, and do not use aging, deformed, cracked centrifuge tubes.
6. Leave after the last routine safety check using a centrifuge on holidays and evenings.
VII. In the event of machine failure during the use of the instrument, contact the technician in time for damage to the component.
Operational considerations
1. To ensure safety and centrifugation, the instrument must be placed on a sturdy, level surface. No items should be placed on the engineering plastic door; the samples must be placed symmetrically and the nut must be tightened before starting.
2. Before use, check the rotor for any flaws, corrosion, etc. At the same time, check the centrifugal cup for cracks, aging, etc. If you find any doubt, stop using it immediately and contact the factory; be sure to tighten the rotor before starting the machine. Press the nut to prevent the high-speed rotating rotor from flying out and causing an accident.
3. The speed setting must not exceed the maximum speed to ensure safe operation of the machine.
4. If 0.00 or other digits appear during use, the machine will not be turned off, and should be turned off and off. After 10 seconds, turn it back on. After the set speed is displayed, press the operation button again, the machine will run as usual.
5. If the specific gravity of the sample to be separated exceeds 1.2 g/cm 3 , the maximum speed N must be corrected as follows: N = N MAX * (1.2 / sample specific gravity) 1/2 , N MAX = rotor limit speed.
6. Do not open the door during the operation of the machine or when the rotor is not stopped to avoid accidents.
7. The centrifuge cup must be filled with the same amount of sample, so do not run the rotor under unbalanced conditions.
8. It is best not to run the centrifuge for more than 60 minutes at a time.
9. The centrifuge must be grounded reliably; if the machine is not in use, unplug the power cord.
