switch (6b). Take a look through the eyepiece
and adjust the light so that you get optimal
picture brightness. Now you can observe in the
same way as described in point 1.3.
The bulbs for the electric light can be
replaced. When you use another bulb, make
sure to pay attention to the maximum wattage,
which is displayed on the lamp body.
TIP: The higher the magnification used,
the more light is required for a good
illumination of the picture. Therefore, always
start your experiments with one of the lower
magnifications.
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.
Using 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 (13). Then, add a few
drops of distilled water on the object using a
pipette. Now, place a cover slip (12) 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
wiped clean using little pressure.
Make sure your microscope is always protect-
ed 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.
