6.1 Cleaning Optical Components
Do not allow dust, fingerprints, or any other dirt to get on the optical components (i.e. lenses and filters). Dirt
on optical components will degrade the image quality. If an optical component becomes dirty, clean them as
described below.
• Remove any dust by brushing off with a soft brush or by wiping gently with gauze.
• If and only if there are fingerprints or grease on the optical component, wipe gently with a piece of soft,
clean lens tissue, cotton cloth, or gauze dampened with a small amount of absolute alcohol (ethyl or
methyl).
• When removing immersion oil from an objective, use only petroleum benzine. After wiping with petroleum
benzine, wipe with absolute alcohol (ethyl or methyl) for a better finish.
If petroleum benzine is unavailable, use methyl alcohol. However, as methyl alcohol does not clean as
well as petroleum benzine, it will be necessary to wipe a few more times (usually three to four wipes).
• Never use petroleum benzine to clean the entrance lens or the prism surface of the eyepiece tube.
• Absolute alcohol is highly flammable. Handle with care. Do not use near an open flame, or operate a
power switch in the vicinity.
• When using absolute alcohol, follow the instructions provided by the manufacturer.
6.2 Cleaning the Microscope Body
• Use silicon cloth to clean the microscope body.
• For persistent dirt, dampen a piece of gauze with neutral detergent and wipe gently.
• Do not use organic solvents. They may cause discoloration of plastic parts.
6.3 Disinfecting the Microscope
• Use a 70% medical alcohol for disinfection.
• If a specimen is spilt onto the microscope, check if the specimen is hazardous. If the specimen is
hazardous, follow the standard procedures for your facility.
• Do not use organic solvents. The may cause discoloration of plastic parts.
6.4 Storage
• Store the product in a dry location where mold is unlikely to grow.
• Store the objectives and eyepieces in a desiccator or equivalent, along with some desiccant.
• Put a dust-proof cover over the product to protect it from dust.
• Before putting on the dust-proof cover, turn off the power switch on the equipment (press the “OFF” side
or the “O” side) and wait until the lamp has cooled sufficiently.
