The laboratory is commonly used electric centrifuge electric centrifuge rotation speed is fast, pay attention to safety, especially to prevent during the operation of the centrifuge, due to imbalance or aging of the test tube mat, so that the centrifuge moves while working, falls from the experimental bench, or because the lid is not covered, the centrifugal tube is broken due to vibration, and the glass fragments rotate out, causing an accident. Therefore, when using a centrifuge, you must pay attention to the following operations. Rules of use
1. When the centrifuge is in the pre-cooling state, the centrifuge cover must be closed, and the rotary head taken out after the centrifuge is finished should be placed on the experimental bench to dry the remaining water in the chamber. At this time, the centrifuge cover is in the open state.
2. The swivel head can be placed on the platform of the centrifuge or placed on the test bench when the swivel head is pre-cooled, and must not be tightened to float on the swivel head, because once it is mistakenly started, the swivel head will fly out, causing an accident!
3. After tightening the turnhead cover, be sure to touch the gap between the turnhead and the turnhead with your fingers. If there is a gap, unscrew and tighten it again until it is confirmed that there is no gap before starting the centrifuge.
4. During the centrifuge process, the operator shall not leave the centrifuge room. In case of abnormal situation, the operator shall not turn off the POWER, and press STOP. Fill out centrifuge usage record before pre-cooling.
5. Do not use shoddy centrifugal tubes, do not use aging, deformed, cracked centrifugal tubes.
6. The last person to use the centrifuge on holidays and at night must undergo a routine safety check before leaving.
7. When machine failure occurs during the use of the instrument and parts are damaged, contact the manufacturer in time
Precautions for the use of centrifuges: It is my own summary, there are many loopholes, please forgive me
Just three:
1. When placing the centrifugal tube, be sure to place it symmetrically!! In this way, it can be turned to ensure that it is not biased, for example, there are four positions for placing centrifugal tubes, and you must put two centrifugal tubes and put one other
2. Be sure to close the cover of the centrifuge when opening it
3. When opening and closing the centrifuge, the speed must be slowly increased or decreased, and the speed cannot be changed quickly at once
