How do I make thin specimen slices?
Only do this with the supervision of your par-
ents or another adult.
In order to get the best results, you will need
some wax or paraffin. It is best if you use a can-
dle. Place the wax in a pot and heat it carefully
over a low heat. Now, dip the object in the liquid
wax a few times. Then, let the wax get hard. Us-
ing the Specimen slicer (17) or a knife/scalpel,
cut the smallest slices from the object that is
covered with wax. These slices are to be laid on
a slide and covered with a cover slip.
How do I make my own specimens?
Take the object that you want to observe and
place it on a glass slide (14). Then, add a few
drops of distilled water on the object using a
pipette. Now, place a cover slip vertically at the
edge of the drop of water, so that the water runs
along the edge of the cover slip. Then, slowly
lower the cover slip over the water drops.

Make sure your microscope has a long service
life.
Clean the lens (objective and eyepiece) only
with the cloth supplied or some other soft lint-
free cloth (e.g.microfibre). Do not press hard as
this might scratch the lens.
Ask your parents to help if your microscope is
really very dirty. The cleaning cloth should be
moistened with cleaning fluid and the lens wi-
ped clean using little pressure.
Make sure your microscope is always protec-
ted against dust and dirt. After use leave it in
a warm room to dry off. Then install the dust
caps and keep it in the case provided.
