High-speed refrigerated centrifuge operation steps

1. Turn on the centrifuge switch and enter the standby state. If the centrifuge is refrigerated , it must be turned on 10 minutes in advance and needs to be pre-cooled.

2. Choose the right rotor: the liquid in the centrifuge tube can not exceed 2/3 of the total capacity when centrifuged, otherwise liquid, easy

In the overflow; attention should be paid to the presence or absence of leakage of liquid in the rotor before and after use, and should be kept dry. Conversion

Care should be taken to lock the screws of the centrifuge shaft and the rotor when turning the head.

2. Centrifuge tube balance error should be within 1 gram.

3. Select the centrifugal parameters :

a) Press the temperature setting button, then use the numeric keys to set the centrifugal temperature and press Enter to confirm.

b) Press the speed setting button to switch between RPM/RCF setting files and set the centrifugal speed with the number keys.

Enter to confirm.

c) Press the rotor setting button, then use the number keys to set the rotor model and press Enter to confirm.

d) Press the time setting button, then use the numeric keys to set the centrifugation time and press Enter to confirm.

e) Centrifuge brake or acceleration speed is generally set between 0 and 4, and should not be adjusted frequently.

4. Place the balanced centrifuge tube symmetrically into the rotor. Cover the rotor cover and tighten the screws.

5. Press the centrifuge door. If the door is not closed, the centrifuge will not start.

6. Press the START button to start centrifugation. After the start of centrifugation, the centrifugal speed should be equal to the set speed.

Open, once the centrifuge is found to be abnormal (such as unbalanced, causing the machine to vibrate significantly, or very noisy),

Press the STOP button immediately. If necessary, directly press the power switch to turn off the power, stop the centrifugation, and find out the cause.

7. If the machine is found to be faulty, please contact the relevant personnel in time.

8. Please clean the rotor and centrifuge chamber after use, do not close the centrifuge cover, which will facilitate the evaporation of moisture.

9. You must register after use and indicate the usage.

Precautions

1. When the centrifuge is in the pre-cooling state, the centrifuge lid must be closed. After the centrifugation is finished, the rotor should be placed on the test bench and the residual water in the chamber should be dried. The centrifuge lid is open.

2. When ultracentrifugation, the liquid must be filled with the centrifuge tube. When it is too far away, it needs to be vacuumed. Only when it is full, can the centrifuge tube be deformed. If the seal of the centrifuge tube is poorly sealed, the liquid cannot be filled up to prevent spillage and affect the normal operation of the sensor.

3. Rotating head When pre-cooling, the rotating head cover can be placed on the platform of the centrifuge or placed on the test bench. Do not screw it on the rotating head, because once it is accidentally activated, the rotating head cover Will fly out, causing an accident!

4. 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 before the centrifuge can be started.

5. Always use a grounding wire when using. The material added in the centrifuge tube should be relatively balanced. If the two sides are unbalanced, it will cause great damage to the centrifuge, which will at least shorten the service life of the centrifuge.

6. During the centrifugation process, the operator must not leave the centrifuge room. In case of abnormality, the operator cannot turn off the power (POWER), press STOP. Fill in the centrifuge usage record before pre-cooling.
