The Shanghai Yetuo rotary evaporator is a commonly used laboratory equipment for sample concentration and solvent recovery. Proper maintenance and upkeep are crucial to ensure the normal operation and prolong the service life of the rotary evaporator. This article will introduce the maintenance points of the rotary evaporator, including daily cleaning, component maintenance, seal replacement, and regular inspections.

1. Daily cleaning

Regular cleaning of the rotary evaporator is key to maintaining its normal operation. At the beginning, disconnect the power and wait for the device to cool down. Gently wipe the outer shell, turntable, and other surfaces with a soft cloth or cotton swab to ensure they are free of dust and stains. Be careful not to clean the equipment directly with water to avoid damaging the circuits and components.

2. Component maintenance

The components of the rotary evaporator require regular maintenance and lubrication to ensure its normal operation. Inspect and clean components such as rotary motors, seals, vacuum pumps, and condensers, and lubricate or replace them as needed. Ensure smooth motor rotation, no wear or aging of seals, no blockage or leakage of vacuum pump, and no scaling of condenser.

3. Seal replacement

Seals are crucial for the sealing performance of rotary evaporators. Regularly check the wear and aging of the seals, and replace them promptly if necessary. Ensure the quality and integrity of the seals to avoid sample leakage and reduced drying efficiency.

4. Regular inspections

Regularly check the various indicators of the rotary evaporator to ensure its performance and completeness. Check whether the parameters such as speed control, temperature control, and vacuum degree are normal. If there are any abnormalities, adjust or repair them in a timely manner. Regularly calibrate temperature and vacuum sensors to ensure their accuracy and stability.

5. Storage and transportation

If the rotary evaporator requires long-term storage or transportation, appropriate measures should be taken to protect the equipment. First, conduct comprehensive cleaning and maintenance to ensure that the equipment is in excellent condition. Secondly, avoid exposure to damp, high temperature, or vibrating environments and choose dry and stable storage conditions.

Proper maintenance and upkeep are key to ensuring the normal operation and prolonging the service life of the rotary evaporator. Regular maintenance measures such as daily cleaning, component maintenance, seal replacement, and regular inspections can maintain the good performance and stable operation of the equipment. Meanwhile, proper storage and transportation are also important steps in protecting equipment. Through these maintenance measures, we can utilize the function of the rotary evaporator to improve experimental efficiency and accuracy of results.
