10. Maintenance of the microscope
1. Clean all glass components by wiping gently with gauze. To remove fingerprints or oil
smudges, wipe with gauze slightly moistened with a mixture of ether(75%) and alcohol(25%)
To clean the extremity of an immersion objective, use neutral detergent. Do not use the
ether/alcohol mixture for cleaning , for these will deform the electrically insulated section of the
extremity.
Since solvents such as ether and alcohol are highly flammable, they must be handled
carefully.Be sure to keep these chemical away from open flames or potential sources of
electrical sparks - for example, electrical equipment that is being switched on or off. Also
remember to always use these chemical only in a well-ventilated room.
2. Be sure to clean the oil immersion objective after use. Leaving immersion oil on it will
degrades its performance.
3. Do not attempt to disassemble any part of the microscope.
4. When not using the microscope, make sure to set the main switch to "O"(OFF), confirm that
the lamp housing is cool enough and cover the microscope with the provided dust cover.
