Care and Maintenance
6.1 Cleaning the Lenses
•
Dust is best removed using a soft brush or gauze.
•
More persistent dirt, such as fingerprints, grease and oil, may be removed with clean lens tissue (or soft
cotton, gauze) lightly moistened with absolute alcohol (ethyl alcohol or methyl alcohol).
•
To clean immersion oil off the oil-immersion type objective, use lens tissue, soft cotton or gauze lightly
moistened with petroleum benzine. If petroleum benzine is not available, use methyl alcohol. In this case,
you need to wipe 3 to 4 times because the detergency of the methyl alcohol is somewhat weak.
•
Cleaning the condenser
If the condenser was used with oil immersion, remove the condenser from the microscope and clean the
lens as necessary.
Also ensure that the condenser is removed from the microscope and cleaned as necessary during
regular cleaning operations.
•
Absolute alcohol and petroleum benzine are quite inflammable. Take great care when handling them and
when turning the power switch on and off. Be very careful with fire.
•
When using absolute alcohol and petroleum benzene, follow the instructions provided by the
manufacturer.
6.2 Cleaning the Microscope
•
We recommend that you use a silicon cloth to clean the microscope.
•
For persistent dirt, dampen a piece of gauze with neutral detergent and wipe lightly.
•
Do not use organic solvent (alcohol, ether, or thinner). Doing so may result in discoloration of the coating
and plastic parts or removal of the printed text.
6.3 Disinfecting
the
Microscope
•
We recommend that you use 70% medical alcohol for normal disinfection of the microscope.
•
In case of spillage of a sample to the microscope, determine whether the sample is hazardous.
If the sample is hazardous, follow the standard procedure of your laboratory.
•
Using organic solvent may result in discoloration of the plastic parts.
6.4 Storing the Microscope
•
When the microscope is not in use, put a vinyl dust cover over the product to protect it from dust, and
store it in a dry place where mold is not likely to form.
•
Before covering the microscope with the vinyl cover, unplug the power cord.
•
We especially recommend that the objectives and eyepieces be kept in a container (such as a
desiccator) with desiccant in it.
6.5 Periodical Inspections (Charged)
•
To maintain the performance of the microscope, periodical inspections and maintenance are
recommended.
•
For details, contact your nearest Nikon representative.
