Maintenance leakage of the rotary evaporator is a common failure phenomenon of the evaporator, and frequent leak detection should be taken during use. Phenolphthalein test paper can be used for the leak, because ammonia is alkaline, and the phenolphthalein test paper turns red. When you look at it, the place where it is not frosted somewhere in the evaporator is the leak point. You can also find the leak with soapy water at the leak. Fluorescent evaporator leaks can be checked using halogen lamps and halogen leak detectors, or soapy water can be used to find leaks.
When inspecting, first use the eye to evaporate the tube with oil traces. Because Freon and oil can be mutually soluble, when Freon leaks, it will also seep out from the leak. When using a halogen lamp to detect leaks, if there is a Freon leak, the flame of the halogen lamp will have a blue color, and the color will be slightly green, light green, grass green, purple green, purple, etc. to judge how much Freon leaks. If the flame is dark green or purple, the phosgene in the flame is toxic and cannot be checked by this method for a long time.
Maintenance instructions 1, carefully check the instrument before use, whether the glass bottle is damaged, whether the interfaces are consistent, pay attention to light handling.
2. Wipe each interface with a soft cloth (can be replaced with a napkin) and apply a small amount of vacuum grease. The vacuum grease must be covered after use to prevent the entry of lime sand.
3, each interface can not be screwed too tight, you should loosely loosen the active, to avoid long-term tight lock caused by the connector to die.
4. Turn on the power switch first, then let the machine run from slow to fast. When the machine is stopped, stop the machine and turn off the switch.
5, the PTFE switch everywhere can not be tightened too much, easy to damage the glass.
6. Every time you use it, you must wipe off all kinds of oil stains, stains and solvents left on the surface of the machine with a soft cloth and keep it clean.
7. Loosen the PTFE switches after stopping, and the PTFE piston will be deformed when it is still working for a long time.
8. Regularly clean the sealing ring by removing the sealing ring and checking if there is dirt on the shaft. Wipe it with a soft cloth, then apply a little vacuum grease and reinstall it to keep the shaft and seal ring smooth.
9, the electrical part must not enter the water, it is strictly prohibited to get wet.
10, must purchase the original authentic accessories, free use of other accessories can cause fatal damage to the machine.
11. When doing any repairs or inspections on the machine, be sure to cut off the power supply and water source. Note that this equipment is a fragile product, please be careful when using it, and the damage of fragile goods is not covered by our warranty.
