There will be some problems of dirt and wear when the rotary evaporator is used, which will have a certain impact on the performance of the rotary evaporator. In order to ensure the normal operation of the rotary evaporator, we need to maintain the rotary evaporator.
1. Before using the rotary evaporator, carefully check whether the glass bottle is damaged and whether the interfaces are consistent.
2. Each interface shall not be screwed too tightly to avoid locking of the connector for a long time.
3. The water bath pan must be filled with water before turning on the heating switch. When the machine is shut down, the machine must be in a standstill state before turning off the power supply.
4. PTFE switch cannot be tightened, otherwise the glass may be damaged easily.
5. After each use, use gauze to clean up oil stains, stains and other residues on the machine surface.
6. After the experiment is completed, release the PTFE switch, and the PTFE will deform if it is in the working state for a long time.
7. Clean the seal ring regularly, apply a little vacuum grease, and keep the shaft and seal ring lubricated.
8. The electrical components shall not be affected by water and moisture.
