2Every time the instrument is used, it must be registered
3The density of the centrifuged samples should be the same, and the volume of the samples should be 3mm away from the mouth of the test tube
4Place the centrifuged tubes which are flattened, of the same density and with dry walls into the bucket symmetrically and tighten the caps of the corresponding buckets to the corresponding bucket racks, and also the empty buckets should be hanged.
5Turn on the power switch of the instrument
6Press the pedal with your foot and press the specified position with your hand at the same time, the door cover will be opened automatically
7Place the rotary head of the hanging bucket downward and gently put it on the drive shaft sleeve to make sure that it is firm
8Screw the cover of the rotary head tightly
9Press the cover of the door with your hand at the specified position
10Setting Centrifugation parameters: rotor type, speed, temperature, time, lift speed frequency
11Parameter setting confirmation is correct, press ENTER, START
12The centrifuge reaches the set speed for 5 minutes before the user can leave. Centrifugation halfway need to observe whether the instrument is running normally
13 centrifugation end (or press STOP to end the run), the rotor head to stop running, open the door cover, loosen the rotor head cover, the rotor head out to the special rack
14 take out the bucket, loosen the bucket cap, the samples will be taken out
15 bucket and the bucket cap is open in a designated location, if there is a leakage night, take out the sealing ring, wash it and then inverted on the designated location
12 parameters are confirmed to be correct, press ENTER, START If there is any leakage, take out the sealing ring, wash it and then place it upside down on the tablecloth
16Turn off the power of the instrument
17Condensate in the chamber is wiped off
18Close the door cover when the temperature of the chamber is the same as the room temperature
Cautions:
When the frozen centrifugation needs to be pre-cooled, the centrifuge centrifuge centrifuges at the desired temperature for 3-5 minutes at 2000 revolutions per minute
The second, Precautions
1. Please read this manual in detail before using the instrument to avoid misuse.
2. Place the instrument on a solid and flat surface to avoid unnecessary trouble during operation.
3. Plexiglass cover can not be stacked on top of the object, so as not to crush or uneven, affecting the use of the instrument.
4. Do not open the plexiglass cover when the instrument is rotating at high speed.
5. The plug of the power cord, one end is inserted into the socket at the back of the instrument, and the other end is connected to the socket of the external power grid.
Note: When the instrument is not in use, please remove the end connected to the external power grid.
6. The instrument must be operated in accordance with the provisions of Article 5 of the operating procedures, otherwise the motor will be burned out and cannot be used.
7. The centrifuge tube must be checked frequently for cracks, aging, etc. before use, and should be replaced promptly if there is any.
8. After use, wipe the rotary head and the instrument clean, in order to prevent the test liquid staining and corrosion.
9. If the specific gravity of the sample is more than 1.2g/cm3, the maximum speed must be corrected according to the following formula:
n=nMax×1.2÷specific gravity of the sample
nMax...... Limit Rotation Speed
10. When the length of the motor carbon brushes is less than 6mm, it must be replaced in time.
