You should perform these checks before experimenting with centrifuge operation!

When the laboratory centrifuge is turned on, we need to check its rotational speed to see if it is within the range of the rotational speed corresponding to the rotor.
Of course, we also need to check if the rotor parts are loose, how the wiring is connected, and the power supply.
Check whether the connection is normal, etc.
before starting up
.

If he has abnormal shaking or sound, we will stop it immediately for inspection, and make corresponding records
.

Before the centrifuge is used, we have to adjust its braking equipment.
If the rotor of the centrifuge exceeds the corresponding speed when rotating, it needs to be stopped
.

When the rotor is running, we cannot disassemble and adjust it
.

The centrifuge is widely used, and laboratory personnel should be familiar with its use method.
1.
The centrifuge should be placed on a level and firm floor or platform, and strive to keep the machine in a horizontal position to avoid machine vibration during centrifugation
.

2.
Turn on the power switch, install the required rotor as required, and place the pre-balanced sample on the rotor sample rack (the centrifuge tube must be balanced with the sample at the same time).
If there is only one sample tube, the other The support should be replaced with water of the same quality; the centrifuge tube must be placed in the casing symmetrically to prevent the body from vibrating.
Close the cover
.

 　　3.
Press the function selection button to set various requirements: temperature, speed, time, acceleration and deceleration.
For machines with computer control, you need to press the save button to memorize the input information
.

 　　4.
When starting the centrifuge, cover the top cover of the centrifuge before starting slowly
.

 　　5.
Press the start button, the refrigerated centrifuge will operate according to the above parameters, and automatically shut down at the predetermined time
.

 　　6.
After the refrigerated centrifuge has completely stopped rotating, open the cover, take out the centrifuged sample, wipe the rotor and the inner wall of the machine cavity with a soft clean cloth, and cover the machine cover after the temperature in the centrifuge cavity is balanced with room temperature
.

 　　7.
Cotton or test tube pads should be placed at the bottom of the centrifuge casing.
8.
After the separation is completed, first turn off the centrifuge.
After the centrifuge stops rotating, open the centrifuge cover and take out the sample.
Do not use external force to force it to stop moving; 9 .
If the electric centrifuge has noise or the body vibrates, the power supply should be cut off immediately, and the fault should be eliminated immediately;
