A layer of vacuum grease is required before the rotary evaporator is installed.

After opening the vacuum pump, it is found that the vacuum can not be checked. It should be checked whether the bottle mouth is well sealed, whether the vacuum pump itself leaks, whether the sealing ring at the shaft is placed intact, and a vacuum switch connected in the external vacuum tube can improve the recovery rate and evaporation speed.


Using the system vacuum negative pressure, the liquid material can be sucked into the rotating bottle at the feeding port by a hose, and the liquid material should not exceed half of the rotating bottle. The instrument can be continuously fed, and attention should be paid when feeding. 1. Turn off the vacuum pump 2/stop heating 3. After the evaporation stops, slowly open the tube cock to prevent backflow.


The instrument is equipped with a specially designed water bath, which must be energized after adding water. The temperature control scale is 0-99 °C for reference. Due to the existence of thermal inertia, the actual water temperature is about 2 degrees higher than the set temperature. The set value can be corrected when used. For example, you need water temperature 1/3-1/2. Use the connector to remove the power plug.


Turn on the electrical box switch and adjust the knob to the optimum evaporation speed. Take care to avoid fluctuations in the water bath and turn on the cooling water.

Recycling solvent

First open the feed switch to deflate, then turn off the vacuum pump and take out the solvent in the collection bottle.


â—†The equipment needs to be coated with a layer of vacuum grease before installation, seal sealing ring and joint before installation.

â—†The heating tank must be filled with water before it is energized. It is not allowed to dry without water.

â—†RE-201D must be screwed into the fuse hole (19) to avoid damage to the flask.

â—† If the vacuum cannot be pumped up, check it:

1 joints, whether the interface is sealed 2 seals, whether the sealing surface is effective
