Matters needing attention in the use of centrifuges
Centrifuge is an important precision equipment for biochemical experiment teaching and research. Serious accidents may occur if it is improperly used or lacks regular maintenance. Therefore, the operation rules must be strictly observed when using centrifuge.
1. When using various centrifuges, the centrifugal tube and its contents must be accurately balanced on the balance in advance. The difference of weight in balancing should not exceed the range specified in the instructions of each centrifuge. Each centrifuge has its own allowable difference for different turners. The single number of tubes can not be loaded in the turners, when the Turners are only partially loaded. When loading, the pipes must be placed symmetrically in the turning head so that the load can be evenly distributed around the turning head.
2. When loading solution, it should be carried out according to the specific operation instructions of various centrifuges. According to the nature and volume of the liquid waiting for centrifuge, suitable centrifugal tube should be selected. There is no cap on the centrifugal tube, and the liquid should not be loaded too much, so as to prevent the centrifugal from throwing out, resulting in imbalance of the rotating head, rusting or corrosion, while the preparative super-speed centrifuge should be separated. Heart tube, it is often required to fill the liquid, so as not to centrifuge plastic centrifugal tube of the upper depression deformation. After each use, the turning head must be carefully checked, cleaned and dried in time. The turning head is the key part to be protected in centrifuge. When moving, it should be careful not to collide, avoid Matters needing attention in the use of centrifuges
causing scars. The turning head should not be used for a long time. It should be protected by a layer of light wax on the drawing. It is strictly forbidden to use centrifugal tubes with obvious deformation, damage or aging.
3. In order to centrifuge at a temperature below room temperature, the turning head should be placed in the refrigerator or in the turning room of the centrifuge before use.
4. In the centrifugal process, it is not allowed to leave at will. The digital display on the centrifuge should be observed at any time to see if it works properly. If there is abnormal sound, the centrifuge should be stopped immediately to check and troubleshoot in time.
5. Each Turner has its maximum allowable speed and cumulative use time. When using the turner, you should consult the instructions and not use it too fast. Each turning head should have a use file to record the accumulated use time. If it exceeds the maximum use limit of the turning head, it must be used at a reduced speed according to the regulations.
