Although rotary evaporators have great features and advantages in application operations, users should pay attention to the following points in daily operation for the maintenance of rotary evaporators: First, before use, carefully check whether the equipment is damaged and whether the interfaces are consistent. Be careful to handle with care: Second, when cleaning, you can wipe each interface with a soft cloth or napkin, and then apply a little vacuum grease. The vacuum grease must be covered after use to prevent dust and sand from entering. Third, do not tighten the interface too much, and loosen it regularly to avoid the connector from being locked for a long time.
Fourth, turn on the power switch first, then let the machine run from slow to fast, and turn off the switch after the machine stops.
Fifth, the polytetrafluoroethylene switches in various places should not be tightened too much, which is easy to damage the glass.
Sixth, after each use of the equipment, use a soft cloth to wipe off all kinds of oil stains, stains, and solvent residues left on the surface of the machine to keep it clean. Loosen each polytetrafluoroethylene switch after shutdown. Long-term static working state will cause the polytetrafluoroethylene piston to deform. In addition, the sealing ring should be cleaned regularly. The specific method is to remove the sealing ring, check whether there is dirt on the shaft, wipe it clean with a soft cloth, then apply a little vacuum grease, and reinstall it to keep the shaft and the sealing ring smooth.
Seventh, the electrical part must not be exposed to water and moisture.
Eighth, users need to purchase genuine accessories from the original factory. Using other accessories at will will cause fatal damage to the machine.
Ninth, when making any repairs or inspections on the machine, first cut off the power supply and water supply, and indicate that this equipment is a fragile product.
