離心機轉子使用壽命說明Centrifuge rotor life of instructions

高速和低速離心機轉子則簡單地用年限來規定轉子壽命，鋁合金轉子一般為7年。這顯然不很科學，部分製造商同時採用運轉次數或運轉時間記錄。如果某個轉子幾乎天天使用20小時，那肯定不能用7年。而離心機買了多年沒用，但已到廠家規定的7年，對這樣的轉子是還可使用，只是適當降速即可。 由於離心樣品大都具有腐蝕性，就連普通的自來水對鋁轉子都有腐蝕。在應力腐蝕與化學腐蝕共存下產生雙重腐蝕疲勞，可導致轉子的實際壽命比保證壽命減少。為了避免發生這種情況，使用者應經常仔細觀察容易發生腐蝕的轉子部位，如試管孔底部、轉子底部與主軸連接處，以及轉子上部大螺紋處等。 對超速離心機轉子，一般規定鋁轉子運轉1,000~1,500次或1,000~1,500小時，此後要降速10%使用同樣的次數和時間；鈦轉子保證使用5,000次或1,0000小時。若有些轉子長期不用，其內部金屬組織會發生變化也應降速使用。廠家保證期限為5年。因此，要求使用者必須堅持記錄每個轉子的運轉次數和累計運轉時間。由於科技的發展，最近的超速離心機轉子有內鑲嵌的智慧記憶系統，自動完成累計記錄，用戶不用自己做記錄。

儀器適當的保養與記錄使用情形，將有助延長儀器使用壽命。

High-speed and low speed centrifuge rotor is simply the life of the provisions of the rotor life, aluminum alloy rotor of 7 years. This is obviously not very scientific, part of the manufacturer at the same time running the number of running time record. If a rotor is almost every day with 20 hours, it certainly can not be used for seven years. Centrifuge to buy years of useless, but to the manufacturers stipulated seven years, so rotor can also use only the appropriate spin-down can be. Centrifuged samples mostly corrosive, and even ordinary tap water has aluminum rotor corrosion. A double corrosion fatigue, stress corrosion and chemical corrosion coexist and can lead to the actual life of the rotor is less than the guaranteed lifetime. In order to avoid this situation, users should always carefully observe the rotor parts prone to corrosion, such as test-tube hole at the bottom of the rotor at the bottom of spindle connections, as well as the rotor upper part of the thread. Ultracentrifuge rotor, the general provisions of the aluminum rotor 1,000 to 1,500 or 1,000 to 1,500 hours of operation, then to slow down to 10% using the same frequency and duration; titanium rotor to ensure the use of $ 5,000 or 1,0000 hours. Some rotor long-term without the internal metal structure will change also should slow down and use. The factory warranty period is five years. Therefore, users must adhere to the operation frequency and cumulative running time of the record of each rotor. Speeding centrifuge rotor due to the development of science and technology, within the mosaic of intelligent memory system, auto-complete cumulative record, users do not own record.
Proper maintenance of records of instrument usage, will help extend the instrument life.
