Shanghai Xinzhuang Instrument Co., Ltd. develops the Rotary Evaporator of Xinzhuang (LNB) brand, which is energy-saving and environmentally friendly. Professional manufacturing is more secure and affordable.
Maintenance instructions
1. Check the instrument carefully before use. Whether the glass bottle is damaged or not, and 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.
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.
Strive for beautiful, practical, stable and cost-effective products, and strive to save more experimental space for our customers. Shanghai Xinzhuang will continue to provide you with safe, stable and high-performance experimental equipment to make your experiment process more Easy.
