VI. Care and maintenance
1. Lens Cleaning
Do not let dust, fingerprints, etc., get on the lenses. Dirt on the lenses, filters, etc., will adversely affect the view of
the image. If any of the lenses get dirty, clean them as described below.
• Either brush away dust with a soft brush, or else wipe it away gently with gauze.
• Only if there are fingerprints or grease on a lens, dampen a piece of soft, clean cotton cloth, lens tissue, or gauze
with absolute alcohol (ethyl or methyl alcohol) and wipe.
• Only when removing the immersion oil off from the objective, use petroleum benzine. If you cannot obtain
petroleum benzine, use methyl alcohol. However, because methyl alcohol does not clean as well as petroleum
benzine, it will be necessary to wipe the surfaces repeatedly. (Usually, three or four times is sufficient to clean the
lenses.)
• Never use petroleum benzine to clean the entrance lens at the bottom of the eyepiece tube or orusn surface of the
eyepiece tube.
• Absolute alcohol and petroleum benzine are highly flammable. Be careful when handling it, when around open
flames, when turning the power switch on / off, etc.
• Follow the instructions provided by the manufacturer when using absolute alcohol.
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.
• Using organic solvents could result in discoloration of the plastic parts.
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 onto the microscope, determine whether the sample is hazardous. If the sample is
hazardous, follow your standard laboratory procedures.
• Using organic solvents could result in discoloration of the plastic parts.
4. Storage
Store the microscope in a dry place where mold is not likely to form.
Store the objectives and eyepieces in a desiccator or similar container with a drying agent.
Put the vinyl cover over the microscope to protect it from dust.
Before putting on the vinyl cover, turn off the power switch on the microscope (flip it to the O side) and wait until the
lamphouse is cool.
5. Periodical inspections (charged)
Periodical inspections (expenses charged) of this microscope are recommended in order to maintain peak
performance. Contact your nearest Nikon representative for details.
