Check the glass bottle of the instrument carefully before using the rotary evaporator
Operation steps After the vacuum pump is turned on, it is found that the vacuum cannot be hit. Check whether the mouth of each bottle is sealed, whether the vacuum pump itself leaks, whether the sealing ring at the shaft is intact, a vacuum switch connected in series with the external vacuum tube can improve the recovery rate Evaporation rate.
The feeding uses the vacuum negative pressure of the system, and the liquid material can be sucked into the rotating bottle with a hose at the feeding port, and the liquid material should not exceed half of the rotating bottle. The instrument can be fed continuously, please pay attention when feeding 1. Turn off the vacuum pump 2 / stop heating 3. After the evaporation stops, slowly open the tube cock to prevent backflow.
This instrument is equipped with a specially designed water bath. It must be filled with water and then powered on. 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 during use, such as: you need the water temperature 1 / 3-1 / 2. Remove the power plug with a pull out.
Turn on the switch of the electric control box, adjust the knob to the best evaporation speed. Pay attention to avoid the vibration of the water bath and connect the cooling water.
To recover the solvent, first open the feed switch to deflate, then turn off the vacuum pump, and remove the solvent in the collection bottle.
Matters needing attentionAt the time of installation, each grinding port, sealing surface seal ring and joint must be coated with vacuum grease before installation.
â—† Water must be added before the heating tank is energized, and dry burning without water is not allowed.
â—† RE-201D must be screwed (19) into the safety hole to prevent damage to the flask.
â—† If the vacuum cannot be pumped up, please check:
①Whether the joints and interfaces are sealed ② Whether the sealing ring and sealing surface are effective ③ Whether the vacuum grease between the main shaft and the sealing ring is coated ④ Whether the vacuum pump and its leather tube are leaking ⑤ Whether the glass parts are cracked, broken or damaged
The maintenance leakage of the rotary evaporator is a common failure phenomenon of the evaporator, and it should be noted that the leak is frequently checked during use. The leak can be checked with phenolphthalein test paper. Because ammonia is alkaline, it turns red when exposed to phenolphthalein test paper. When you see it with your eyes, the leak point is usually somewhere in the evaporator. You can also use soapy water to find the leak. The inspection of Freon evaporator leaks can use halogen lamps and halogen leak detectors, or use soapy water to find leaks. During the inspection, you can first use the eye to see if there is oil on the evaporation pipe, because Freon and oil can be miscible, and when Freon leaks, it may also leak out from the leakage point. When using a halogen lamp to detect leaks, if there is a Freon leak, the flame of the halogen lamp will turn blue, light green, grass green, purple green, purple and other colors to determine how much Freon leaks. If the flame is dark green or purple, the phosgene in the flame is poisonous and cannot be checked by this method for a long time.
Maintenance instructions
1. Check the instrument carefully before use, whether the glass bottle is damaged, and whether the interfaces are consistent, pay attention to take it lightly.2. Wipe each interface with a soft cloth (can be replaced with a napkin), then apply a little vacuum grease. The vacuum grease must be covered after use to prevent the ingress of lime sand.
3. Each interface should not be tightened too tightly, and it should be loosened regularly to avoid the connector biting due to long-term locking.
4. First turn on the power switch, and then let the machine run from slow to fast. When the machine is stopped, the machine should be in a stopped state before turning off the switch.
5. The PTFE switches everywhere can't be tightened excessively, which is easy to damage the glass.
6. Every time you use it, you must use a soft cloth to wipe off all the oil marks, stains and solvents left on the surface of the machine, and keep it clean.
7. Loosen the PTFE switches after shutdown, and the PTFE piston will be deformed when it is still in working condition for a long time.
8. Regularly clean the sealing ring by removing the sealing ring, checking whether there is dirt on the shaft, wiping it with a soft cloth, then applying a little vacuum grease, and reinstalling it to keep the shaft and the sealing ring smooth.
9. The electrical part must not enter the water, and it is strictly forbidden to get wet.
10. It is necessary to purchase the original genuine parts of the original factory, and the use of other parts at will will cause fatal damage to the machine.
11. When doing any repair or inspection on the machine, be sure to cut off the power supply and water source first. Note that this equipment is a fragile product, please be careful when using it. The damage of fragile products is not covered by our warranty.
