3.10 Care, Maintenance and Troubleshooting
3.11 Instrument Care
Care of the microscope is restricted to the following operations:
• Cover the instrument with the dust cover after every use and do not expose the instrument to
ultraviolet radiation without any protection.
• Do not install the microscope in a humid room; maximum humidity < 75%.
• Cover open tubes with the dust caps.
• Remove dust and loose dirt from visible optical surfaces with a brush, blower brush, cotton swab,
optics cleaning tissue, or a cotton cloth.
• Remove water-soluble dirt (coffee, cola, etc.) by blowing on it and then wiping it off with a dust-free
cotton cloth or a cloth moistened with water to which you may also add a mild detergent.
• Wipe off stubborn oily or fatty dirt (immersion oil, fingerprints) with cotton cloths or a dust-free cotton
cloth moistened with the optics cleaning solution L.
The cleaning solution consists of 90 vol% gasoline and 10 vol% isopropanol (IPA). Its individual
constituents are also known as:
Gasoline: Surgical spirit, petroleum ether
Isopropanol: 2-propanol,
dimethyl carbinol,
2-hydroxypropane
Clean optical surfaces by polishing them in circles from the middle and to the edges using slight pressure
only.
Before cleaning the plug-in power unit, disconnect it from line power. Avoid in any case the penetration
of moisture into the plug-in power unit.
For using the microscope in warm and humid climatic zones, it comes with all optical components already
protected against fungus attack.
