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 are backwards.
5. Insert the feed tube into the condenser tube.
6. Dock the collection bottle with the condenser tube and clip it with the bottle mouth clamp.
7. Place the rotating bottle on the right end of the rotating shaft and clamp it with the bottle mouth clamp.
8. Place the water bath under the rotating bottle and add clean water to the 2/3 pot (the tap water should be placed for 1-2 days)
9. Connect the vacuum tube joint with the vacuum tube at the suction pipe and the vacuum pump or laboratory vacuum switch for the other joint.
10. The joints (2) and (3) are connected to the cooling water, and the joint (4) is connected to the feeding tube.
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 at 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: open the electric control box switch, adjust the rotation to zui good evaporation speed. Take care to avoid fluctuations in the water bath vibration.
5. Turn on the cooling water.
6. Recover solvent: Turn off the vacuum pump, open the feed switch to deflate, and take out the solvent in the collection bottle.
