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?

In the base of the microscope there is a battery compartment (10). Loosen the screw at the battery compartment cover with a small Philips screwdriver and re-

move the cover. Place the batteries in the compartment so that the flat minus poles (-) press against the spring terminal and the plus poles (+) are touching the flat contact sheets.

Close the battery compartment with the cover and turn the microscope around again.

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. There is a selection switch for this (12). It has two numbers: I and II. If you select the ...

12 IOI

I, the light only comes from below (transmitted light).

II, the light only comes from above (reflected light).

For transparent objects (transmitted-light objects), number I is best. In order to observe firm, non-transparent objects (direct-light objects), select number II.

When do I use the color filters?

The color filter wheel (27) is located below the microscope stage (7). 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 components of colorless or transparent objects (e.g. grains of starch, protozoa).

How do I adjust my microscope correctly?

Each observation starts with the lowest magnification.

Adjust the microscope stage (7) so that it goes all the way down to the lowest position (11). Then, turn the objective

nosepiece (4) until it clicks into place at the lowest magnification (objective 4x).

Note:

Before you change the objective setting, always move the microscope stage (7) to its lowest position. This way, you can avoid causing any damage!

Now insert the smallest eyepiece, in this case the WF10x (1) into the eyepiece support (3).

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 you will require for a good image quality.

Now place the prepared specimen (14) directly under the objective on the microscope stage. The object should be located directly over the illumination (8).

In the next step, take a look through the eyepiece (1) and carefully turn the focus knob (11) until the image appears clear and sharp. If you would like an even higher level of magnification, insert the 20x eyepiece (2) and turn the objective nosepiece (4) to a higher setting (10x or 40x).

Important tip:

The highest magnification is not always best for every specimen!

Note:

Each time the magnification changes (eyepiece or objective change), the image sharpness must be readjusted with the focus knob (11). 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!

more light

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 observation 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 transparent 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 (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.

Experiments

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 interesting 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.

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!
