Rotary evaporator is a commonly used Laboratory equipment for sample concentration and solvent recovery. In order to ensure the normal operation of the Rotary evaporator and extend its service life, correct maintenance is very important. This article will introduce the maintenance points of the Rotary evaporator, including daily cleaning, parts maintenance, seal replacement and regular inspection.

1. Daily cleaning

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

2. Component maintenance

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

3. Seal replacement

The sealing element is very important for the sealing performance of the Rotary evaporator. Regularly check the wear and aging degree of the sealing components, and replace them in a timely manner if necessary. Ensure the quality and integrity of the seals to avoid sample leakage and reduced drying effectiveness.

4. Regular inspection

Regularly check the indicators of the Rotary evaporator to ensure its performance and integrity. Check whether the parameters such as speed control, temperature control and vacuum degree are normal, and timely adjust or repair if there is any abnormality. Regularly calibrate temperature and vacuum sensors to ensure their accuracy and stability.

5. Storage and Transportation

If the Rotary evaporator needs long-term storage or transportation, appropriate measures shall be taken to protect the equipment. Advanced comprehensive cleaning and maintenance to ensure that the equipment is in excellent condition. Secondly, avoid exposure to damp, high temperature, or vibration environments and choose dry and stable storage conditions.

Correct maintenance is the key to ensure the normal operation of the Rotary evaporator and extend its service life. Regular maintenance measures such as daily cleaning, component maintenance, seal replacement, and regular inspection can maintain the good performance and stable operation of the equipment. At the same time, proper storage and transportation are also important aspects of protecting equipment. Through these maintenance measures, we can give full play to the function of the Rotary evaporator and improve the efficiency of the experiment and the accuracy of the results.
