Precautions for using a centrifuge

1. In order to ensure safety and centrifugal effect, the instrument must be placed on a sturdy and level tabletop, and no objects must be placed on the engineering plastic cover door; The sample must be placed symmetrically and the nut must be tightened before starting up.

2. Before use, the rotor should be checked for scratches, corrosion, and other phenomena. At the same time, the centrifugal cup should be inspected for cracks, aging, and other aspects. If any doubts are found, the use should be stopped immediately and the manufacturer should be contacted; Before starting up, please make sure to tighten the clamping nut of the rotor to prevent accidents caused by the high-speed rotation of the rotor flying out.

3. The speed setting should not exceed the maximum speed to ensure safe operation of the machine.

4. If 0.00 or other numbers appear during use and the machine does not operate, it should be shut down and powered off. After 10 seconds, it should be restarted. After the set speed is displayed, press the operation button again, and the machine will operate as usual.

5. If the specific gravity of the sample to be separated exceeds 1.2 grams per cubic centimeter, the maximum speed N must be corrected according to the following formula: N=NMAX * (1.2/sample specific gravity) 1/2, NMAX=rotor limit speed.

6. Do not open the cover door while the machine is running or the rotor is not stationary to avoid accidents.

7. The centrifuge cup must be filled with an equal amount of sample, and the rotor must not be operated in an unbalanced state.

8. It is best not to run the centrifuge for more than 60 minutes at a time.

9. The centrifuge must be reliably grounded; The machine is not in use, please unplug the power plug.
