14. Care
Caution!
Unplug the power supply before performing cleaning and maintenance work!
Protect electrical components from moisture!
Microscopes in warm and warm-damp climatic zones require special care in order to prevent the build up of
fungus.
The microscope should be cleaned after each use, and the microscope optics should be kept painstakingly
clean.
14.1 Cleaning
!
Caution:
Residual fiber and dust can create unwanted background fluorescence during fluorescence microscopy.
Cleaning coated parts
Dust and loose dirt particles can be removed with a soft brush or lint-free cotton cloth.
Clinging dirt can be cleaned as necessary with a low-concentrated soap solution, petroleum ether or ethyl
alcohol.
For cleaning coated parts, use a linen or leather cloth that is moistened with one of these substances.
!
Caution:
Thinners containing acetone, xylene or nitrogen can harm the microscope and thus must not be used.
Test cleaning solutions of unknown composition on a less visible area of the unit first. Be sure that coated or
plastic surfaces do not become matted or etched.
14.2 Handling acids and bases
For examinations using acids or other aggressive chemicals, particular caution must be taken.
!
Caution:
Never allow the optics and mechanical parts to come into direct contact with these chemicals.
Removing immersion oil
Caution!
Follow safety notes for immersion oil!
First, wipe off the immersion oil with a clean cotton cloth, and then re-wipe the surface several times with
ethyl alcohol.
