How do I use my microscope?
Before you assemble your microscope, make sure that the table, desk or
whatever surface that you want to place it on is stable, and does not wobble.
How do I operate the electric LED illumination?
The batteries supplied should be inserted into the battery compartment (15)
located in the base plate before use.
Remove the battery compartment cover by pressing lightly on the cover clip.
Insert the batteries (3x AA) into the holder.
There are two lights on the microscope. They do not use light bulbs, but rather light-emitting diodes (LED). The first lamp shines onto the specimen from below and the second from above. (The thing that you want to observe with the microscope is called the object or specimen, by the way.) You can use each lamp on its own, or both of them together. There is a selection knob for this (Fig. 1, 14). It has three numbers: I, II and III. If you select the …
I, the light only comes from below (transmitted light).
II, the light only comes from above (reflected light).
III, both lamps shine light on the specimen.
For transparent objects (transmitted-light objects), number I is best. In
order to observe firm, non-transparent objects (direct-light objects), select
number II. For semi- transparent objects, it is best to select number III.
It is not recommended to use number III for transmitted-light objects on
slides, since the light may cause reflections on the surface of the slide,
which will disturb your observation.
When do I use the color filters?
The color filters (Fig. 1, 17) are located below the microscope stage (Fig. 1,
11). They help you when you are observing very bright or clear specimens.
Here, you can choose from various colors. This helps you better recognize the
com- ponents of colorless or transparent objects (e.g. grains of starch,
protozoa).
How do I adjust my microscope correctly?
First, loosen the screw (Fig. 1, 7) and turn the microscope head (Fig. 1, 6)
into a comfortable viewing position.
Each observation starts with the lowest magnification.
Adjust the microscope stage (Fig. 1, 11) so that it goes all the way down to the lowest position. Then, turn the objective nosepiece (Fig. 1, 8) until it clicks into place at the lowest magnification (objective 4x).
Note:
Before you change the objective setting, always move the microscope stage
(Fig. 1, 11) to its lowest position. This way, you can avoid causing any
damage!
Now, insert the 10x eyepiece (Fig. 1, 1) into the Barlow lens (Fig. 1, 3). Make sure that the Barlow lens is placed all the way into the eyepiece supports (Fig. 1, 5) and is not pulled out (Fig. 2).
How do I observe the specimen?
After you have assembled the microscope with the adequate illumination and
adjusted it correctly, the following basic rules are to be observed:
Start with a simple observation at the lowest magnification. This way, it is
easier to position the object in the middle (centering) and make the image
sharp (focusing).
The higher the magnification, the more light you will require for a good image
quality.
Now place the prepared specimen (Fig. 6, 20) directly under the objective on the microscope stage (Fig. 3). The object should be located di-rectly over the illumination (Fig. 1, 12).
In the next step, take a look through the eyepiece (Fig. 1, 1) and carefully
turn the focus knob (Fig. 1, 16) until the image appears clear and sharp. Now
you can select a higher magnification by slowly removing the Barlow lens (Fig.
1, 3) from the eyepiece support (Fig. 1, 5). When the Barlow lens is almost
completely pulled out, the magnification can be increased to almost double.
If you would like an even higher level of magnification, insert the 16x
eyepiece (Fig. 1, 2) and turn the objective nosepiece (Fig. 1, 8) to a higher
setting (10x or 40x).
Important tip:
The highest magnification is not always the best for every specimen!
Note:
Each time the magnification changes (eyepiece or objective change, pulling out
the Barlow lens), the image sharpness must be readjusted with the focus knob
(Fig. 1, 16). When doing this, make sure to be careful. If you move the
microscope stage too quickly, the objective and the slide could come into
contact and become damaged!
Which light for which specimen?
With this unit, a reflected light and transmitted light microscope, you can
observe transparent, semi-transparent as well as non-transparent objects. The
image of the given object of obser- vation is “transported” through the light.
As a result, only the correct light will allow you to see something!
If you are observing non-transparent (opaque) objects (e.g. small animals,
plant components, stones, coins, etc.) with this microscope, the light falls
on the object that is being observed.
From there, the light is reflected back and passes through the objective and
eyepiece (where it gets magnified) into the eye. This is reflected light
microscopy.
For transparent objections (e.g. protozoa), on the other hand, the light
shines from below, through the opening in the microscope stage and then
through the object.
The light travels further through the objective and eyepiece, where it is also
magnified, and finally goes into the eye. This is transmitted-light
microscopy.
Many microorganisms in water, many plan components and the smallest animal
parts are already transparent in nature. Others have to be prepared. We may
make them ransparent through a treatment or penetration with the right
materials (media), or by taking the thinnest slices from them (using our hand
or a specimen slicer), and then examine them. You can read more about this in
the following sections.
How do I make thin specimen slices?
Only do this with the supervision of your parents or another adult. As I
already pointed out, the thinnest slices possible are taken from an object. In
order to get the best results, we need some wax or paraffin. It is best if you
get a candle. Place the wax in a pot and heat it carefully over a low burner.
Now, dip the object in the liquid wax a few times. Then, let the wax get hard.
Using the specimen slicer (Fig. 6, 23) 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 (Fig. 6, 20). Then, add a few drops of distilled water on the object (Fig. 7) using a pipette (Fig. 7, 26). 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 (Fig. 8).
Note:
The included glue “gum media” (Fig. 5, 21b) is used to make permanent prepared
specimens. Use this in place of the distilled water. If you want to keep the
object in place on the slide permanently, use the gum media.
Troubleshooting
| Error | Solution |
|---|---|
| No recognizable image | • Turn on light |

Smartphone holder
Open the flexible holder and put your smartphone in it. Close the cradle and make sure your phone is properly seated. The camera must be positioned exactly above the eyepiece. Open the locking clip on the back of the holder and fit the eyepiece view exactly onto your smartphone camera. Now retighten the locking clip and attach the smartphone holder to the eyepiece of your microscope. Now start the camera app. If the image is not yet centered on your display, loosen the locking clip slightly and readjust. It may be necessary to use the zoom function to fill the image on the display. A slight shading at the edges is possible. Remove the smartphone from the cradle after use!
NOTE:
Make sure that the smartphone cannot slip off the cradle. Bresser GmbH accepts
no liability for damage caused by a dropped smartphone!
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 protected 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.
