Explosion-proof Rotary Evaporator installation steps

1. Rotate the rack on a workbench close to the water source. If it is not flat, you can pad four hard rubber feet.
2. Move the center of the machine head to the height of 48cm from the chassis and tilt it to the right by about 25 degrees to lock the lock nuts on the frame.
3. Fix the electric control box as shown in the figure and insert the five-pin plug of the motor.
4. Insert the condenser into the interface of the machine head, adjust each movable joint so that the condenser is vertical and hold with the fixed clamp. The condenser joints of the condenser are backwards.

Explosion-proof rotary evaporator operating steps

1. Vacuuming: 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 rate.
2. Feeding: Using the system vacuum negative pressure, the liquid material can be sucked into the rotating bottle with a hose on the feeding port (4), and the liquid material should not exceed half of the rotating bottle. The instrument can be continuously fed. When feeding, please pay attention to 1 Turn off the vacuum pump 2 Stop heating 3 After the evaporation stops, slowly open the tube cock to prevent backflow.
3. Heating: The instrument is equipped with a specially designed water bath. It 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.
4. Rotation: Turn on the electric control box switch and adjust the rotation to the best evaporation speed. Take care to avoid fluctuations in the water bath vibration.
5. Turn on the cooling water.

6. Recovering the solvent: Turn off the vacuum pump, open the feed switch to deflate, and take out the solvent in the collection bottle.
