Pay attention to the problem of electric use of centrifuges

In enterprises or institutions of research, low-speed experimental centrifuges with a speed of about 3000 rpm have been commonly used, such as 315 type filtration + sedimentation integrated experimental centrifuge, 100 type experimental centrifuge, 200 type experimental centrifuge, etc
.

These centrifuges have a reasonable design, low center of gravity, safety and stability, and have been more widely used
in the preliminary sample analysis of chemical, food, medical and other fields.

Operation method 1, the use of various centrifuges, in advance on the balance precision balance of the centrifuge tube and its contents, balance the weight difference shall not exceed the range specified in the instructions of each centrifuge, each centrifuge different rotor has its own allowable difference, the rotor can not be loaded with a singular number of tubes, when the rotor is only partially loaded, the tubes are placed symmetrically in the rotor, so that the load is evenly distributed around
the rotor.

2.
When
centrifuging at a temperature lower than room temperature.

The rotor should be placed in the refrigerator or placed in the rotor chamber of a centrifuge before use to pre-cool
.

3, the centrifugal process shall not leave at will, should observe whether the instrument on the centrifuge is working normally at any time, if there is an abnormal sound should be immediately stopped for inspection, timely troubleshooting
.

4, each head has its own high allowable speed and use of the accumulation limit *, when using the head to check the instructions, do not use
too fast.

Each rotor must have a usage file that records the accumulated use time, and if the high use limit of the rotor* is exceeded, it must be used
at the prescribed speed reduction.

5, loading the solution, according to the specific operating instructions of various centrifuges, according to the nature and volume of the liquid to be centrifuged to select a suitable centrifuge tube, some centrifuge tubes without a cover, the liquid must not be loaded too much, in order to prevent centrifugal throwing out, resulting in unbalanced rotor, rust or corrosion, and the centrifuge tube of the preparatory ultracentrifuge is often required to fill the liquid, so as not to deform
the upper part of the plastic centrifuge tube during centrifugation.

After each use, carefully check the head, timely cleaning, drying, the head is the centrifuge must be protected parts, move to be careful, can not collide, to avoid scarring, when the head is not used for a long time, to apply a layer of glazing protection, it is strictly forbidden to use significant deformation, damage or aging of the centrifuge tube
