Care and Maintenance
1. Cleaning Lenses
z
Dust is best removed with a soft brush or gauze.
z
More persistent dirt, such as fingerprints, grease and oil, may be removed with soft cotton, lens tissue, or
gauze lightly moistened with absolute alcohol (ethyl alcohol or methyl alcohol).
z
To clean immersion oil off the oil-immersion type objective, use lens tissue, soft cotton or gauze lightly
moistened with petroleum benzine only.
If petroleum benzene is not available, use methyl alcohol. In this case, you need to wipe three or four times
because the detergency of the methyl alcohol is somewhat weak.
z
Do not use petroleum benzine to clean the entrance lens at the bottom of the eyepiece tube or prism
surfaces inside the eyepiece tube.
z
Absolute alcohol and petroleum benzine are quite inflammable. Take great care when handling them and
when setting the power switch on and off. Be very careful with fire
2. Cleaning Painted or Plastic Surfaces
z
Avoid use of any organic solvents (such as alcohol, ether, thinner, etc.) to clean the painted or plastic
surfaces of the instrument. We recommend the use of silicon cloth. More persistent did may be cleaned with
mild detergent solution.
z
Printed plastic surfaces should be cleaned only by soft cloth moistened with water.
3. When Not in Use
z
When the microscope is not in use, cover it up with a vinyl cover, and store it in a dry place not subject to
mold.
z
We especially recommend that the objectives and eyepieces be kept in a container (such as a
desiccators )with desiccant in it
4. Periodical Inspection
z
To maintain the performance of the microscope, periodical inspection is recommended. (Contact your
nearest representative for details.)
