12. Care of the microscope

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
strictly clean.

12.1 Dust cover

Note:
To protect against dust, cover the microscope
and accessories with the dust cover after each
use.
Caution!
Let lamps cool down before covering the
stand with a dust cover. The dust cover is
not heat-resistant. In addition condensation
water may occur.

12.2 Cleaning

!
Caution:
Residual fiber and dust can create unwanted
background fluorescence.
Cleaning coated parts
Dust and loose dirt particles can be removed
with a soft brush or lint-free cotton cloth.
Stubborn dirt can be removed with all commonly
available aqueous solutions, naphtha or alcohol.
For cleaning coated parts, use a linen or leather
cloth that is moistened with one of these sub-
stances.
!
Caution:
Thinners containing acetone, xylene or ni-
trogen can harm the microscope and thus
must not be used.
Test cleaning solutions of unknown composition
first on a less visible area of the unit. Be sure
that coated or plastic surfaces do not become
matted or etched.
Cleaning the stage
Rub the stage with paraffin oil or acid-free Vase-
line to remove light spots on the stage.
