Maintenance and attention of rotating evaporator

1. Carefully check the instrument before use, whether the glass bottle is damaged, whether the interfaces are consistent, and pay attention to light release.

2. Wipe each interface with a soft cloth (instead of a napkin) and apply a little vacuum grease.The vacuum grease must be covered to prevent the sand from entering.

3. The interfaces should not be screwed too tightly, and loosen the active channels regularly, so that the connector will not die due to long-term locking.

4. Turn on the power switch first, and then let the machine run from slow to fast. When the machine is down, stop the machine and turn off the switch.
