An electricity supply is required for observation with the electric illuminator.
Position your device so that it can be disconnected from the power supply at any
time. The wall you use socket should be located near the device and easily accessible, since the plug on the power cord serves as a disconnecting device for
the power supply. Always pull on the plug to separate the device from the power
supply. Never pull on the cord.
2. Electric LED lighting with dimmer
Before use, make sure the light switch (19) is set to 'off'.
The microscope has two light sources. Lighting can be of three types. Set the
switch (19) to 'II' to light the specimen from above (reflected light) or 'I' to light it
from below (transmitted light). Use setting 'III' to light the specimen simultaneously
by transmitted and reflected light. The transmitted light unit (9) is used for transparent specimens (those on glass slides). To view solid, non-transparent specimens,
use the reflected light unit (18). Use of both forms of lighting simultaneously is
only recommended for semitransparent specimens. This operating mode is not
recommended for transmitted light specimens on slides as it may cause reflection
on the slide.
To operate the supplied main power pack (12), first connect it to the microscope
and then to a power socket (220-230V). Use the switch (19) to select the desired
lighting mode.
3. Colour filter disc
The colour filter (17) under the microscope table (7) aids in viewing very bright and
transparent objects. Just select the right colour for the specimen in question. The
components of colourless or transparent objects (e.g. starch particles, single-cell
specimens) can thus be better recognised.
11
4. Interchangeable illumination lenses
6. Observation
Your microscope comes with two illumination lenses (14 and 15). Depending on
the object to be viewed, the proper lens should be attached to the LED illumination
(9). The ground glass, or matted lens (14) is already mounted on the lighting unit.
To change the lenses, simply screw one off and the other on by turning the upper
part of the transmitted light unit (9) (see also page 11).
After you have set up the microscope with the proper illumination, the following
principles are important:
An overview of lens purposes:
The matted lens (14) should be used for
• viewing extremely small items with the eyepieces (1 and 2) and the Barlow lens
(3).
The condenser lens (15) should be used for
• viewing standard items with the eyepieces (1 and 2) and the Barlow lens (3).
5. Microscope setup
The microscope head (5) will now be prepared for your first observation.
First, loosen the screw (16) and rotate the head into a convenient position.
Begin every observation with the lowest magnification.
Place the microscope’s table (7) with the focus knob (8) into the lowest position and
rotate the objective revolver (6) until it locks on the lowest magnification (4X).
NOTE:
Make sure to place the microscope's table (7) in its lowest
position before changing the objective in order to prevent
damage to the microscope.
Insert the 10X eyepiece (No. 1, 1) in the Barlow lens (No. 1, 3).
Take care that the Barlow lens is inserted completely into the monocular head (No.
1, 4).
Begin each observation at the lowest magnification, so that the centre and position
of the object to be viewed is in focus. The higher the magnification, the more light
is required for good picture quality.
Place a permanent slide culture directly under the microscope lens on the plate (7).
The specimen to be examined must be directly over the lighting.
Look through the eyepiece (1 and 2) and carefully turn the focus wheel (8) until you
can see a sharp picture.
Now you can progress to a higher magnification. Slowly pull the Barlow lens (No.
2, 3) out of the monocular barrel (No. 2, 4). When the Barlow lens is nearly entirely
pulled out, the magnification is raised to 2X.
For even higher magnification, you can put the 16X eyepiece (2) into the objective revolver (6) and rotate the objective revolver to a higher magnification (10X or
40X).
i
TIP:
Depending on the preparation, higher magnifications do not
always lead to better pictures.
When changing the magnification of your microscope by changing or adjusting the
eyepiece, objective lens or Barlow lens, you must readjust the focus wheel (8) to
sharpen the image.
NOTE:
Please be very careful when doing this. If you move the mechanical plate upward too fast, the objective lens and the slide can
touch and become damaged.

7. Condition and prepare viewed objects
Place the slices on a glass slide and cover them with another slide before attempting to view them with the microscope.
7.1. Condition
With the Barlow lens nearly fully extended, your microscope's magnification can
be doubled. Both transparent and non-transparent specimens can be examined
with this microscope, which features both direct and transmitted light. If opaque
specimens are being examined, such as small animals, plant parts, tissues, stones
and the like, the light is reflected from the specimen, through the lens and eyepiece, where it is magnified, to the eye (reflected light principle, switch position
I). If opaque specimens are being examined, the light from below goes through
the specimen, lens and eyepiece to the eye and is magnified en route (direct light
principle, switch position II).
Some small water organisms, plant parts and animal components are transparent
by nature, but many others require pretreatment — that is, you need to make a thinnest possible slice of the object by hand cutting or using a microtome, and then
examine this sample.
7.3. Creation of your own preparation
7.2. Creation of thin preparation cuts
8. Experiments
Specimens should be sliced as thin as possible. A little wax or paraffin is needed to
achieve the best results. Put the wax into a heat-safe bowl and heat it over a flame
until the wax is melted. You can use a candle flame to melt the wax.
DANGER!
Be exremely carfeful when dealing with hot wax, as there is a danger
of being burned.
Put the object to be observed on a glass slide and cover the object with a drop of
distilled water (No. 3) using the pipette (No. 3, 20a).
Set a cover glass (available at a well-stocked hobby shop) perpendicular to the
edge of the water drop, so that the water runs along the edge of the cover glass
(No. 4). Now lower now the cover glass slowly over the water drop.
i
TIP:
The gum medium (23b) supplied is used to make permanent slide
cultures. Add it instead of distilled water.
The gum medium hardens so that the specimen is permanently
affixed to its slide.
Now that you're familiar with your microscope's functions and how to prepare
slides, you can complete the following experiments and observe the results under
your microscope.
8.1. Newspaper print
Objects:
Then, dip the specimen several times in the liquid wax. Allow the wax that encases
the specimen to harden. Use a MicroCut (22) or other small knife or scalpel to
make very thin slices of the object in its wax casing.
DANGER!
Be extremely careful when using the MicroCut, knife or scalpel.
These instruments are very sharp and pose a risk of injury.
1. A small piece of paper from a newspaper with parts of a picture and some
letters
2. A similar piece of paper from an illustrated magazine:
Use your microscope at the lowest magnification and make a slide preparation
from each object. Place the slide with the newspaper on the microscope table and
observe the slide. The letters in the newspaper appear broken because the newspaper is printed on raw, inferior paper. Now observe the slide with the magazine
preparation. Letters of the magazine appear smoother and more complete. The
13
picture from the newspaper consists of many small points, which appear somewhat
dirty. The pixels (raster points) of the magazine image appear sharper.
8.2. Textile fibres
Objects and accessories:
1. Threads of different textiles: Cotton, linen, wool, silk, Celanese, nylon and
any others you can find.
2. Two needles:
Put each thread on a glass slide and fray each with the help of the two needles. Put
a drop of water over each thread with the pipette and cover each with a cover glass.
Adjust the microscope to a low magnification. Cotton fibres are of plant origin and
look, under the microscope, like a flat, twisted band. The fibres are thicker and
rounder at the edges than in the centre. Cotton fibres consist primarily of long, collapsed tubes. Linen fibres are also of plant origin; they are round and run in straight
lines. The fibres shine like silk and exhibit numerous swellings along the shaft of
the fibre. Silk is of animal origin and consists of solid fibres of smaller diameter than
the hollow vegetable fibres. Each silk fibre is smooth and even and has the appearance of a small glass rod. Wool fibres are also of animal origin; the surface consists
of overlapping scales, which appear broken and wavy. If possible, compare wool
fibres from different weaving mills, and note the differences in the appearance of
the fibres. Experts can determine the country of origin of wool based on its appearance under a microscope. Celanese is artificially manufactured by a long chemical
process. All Celanese fibres show hard, dark lines on a smooth, shining surface.
The fibres crinkle in the same way after drying. Observe the similarities and differences between the different fibres.
8.3. Saltwater brine shrimps
Accessories:
1. Brine shrimp eggs (23d)
2. Sea salt (23c)
3. Hatchery (21)
4. Yeast (23a)
14
CAREFUL!
These eggs are not fit for human consumption.
8.3.1. Winter eggs of Artemia salina
Artemia salina are species of brine shrimp typically found in salt lakes — bodies of
water with a higher salinity than even the ocean. During a drought, a salt lake can
become a hostile habitat for organisms, and entire populations of Artemia salina
sometimes die off. During drought conditions, to ensure that the species will repopulate the salt lake when the drought ends, Artemia salina lay thick-shelled eggs
called winter eggs that can survive for up to ten years in a dormant state. Winter
eggs can withstand heat, cold and chemicals. These eggs hatch when favourable
conditions return to their ambient environment. The eggs provided (23d) are of
this type.
8.3.2. Hatching winter eggs
To hatch the brine shrimps, create a solution with an appropriate salinity and temperature. First, fill two containers with a half litre of freshwater each, and let them
both stand for about thirty hours. Next, pour half of the provided salt (23c) into one
container and stir the solution until the salt dissolves. Pour some of this solution
into the hatchery (21). Place a few eggs close to the lid. Position the hatchery
somewhere with plenty of light but not in direct sunlight. The ambient temperature
should ideally hover around 25 °C. As water in the hatchery evaporates, gradually
add freshwater from the second container. After two to three days, the eggs will
hatch brine shrimp larvae, called nauplii.
8.3.3. Observing Artemia salina under a microscope
Using the pipette (20a), move some larvae from the container to a microscope slide
for examination. When viewing the larvae, you’ll notice that they swim through the
solution using hairlike limbs! Each day, examine a few more. You can even view the
entire hatchery under the microscope if you remove its lid. The larvae will mature in
six to ten weeks, depending on the temperature of the water. Soon, you will have
an entire generation of saltwater brine shrimps that reproduce frequently!
EN
8.3.4. Feeding your Artemia salina
Feed your brine shrimps often to keep them alive. The best food is dry powdered
yeast (23a). Give them some every other day. Be careful not to overfeed them, as
doing so can cause the water to stagnate and poison the brine shrimps. If the water
does begin to stagnate (you’ll see it darkening), transfer the brine shrimps to the
fresh saline solution you have prepared earlier (see 8.3.2).
Care and maintenance
Before cleaning, separate the device from the power supply by removing the plug.
Only use a dry cloth to clean the exterior of the device.
NOTE:
Do not use any cleaning fluid to avoid damaging the electronics.
Clean the lenses eyepieces and lenses only with a soft, lint-free cloth, like a microfibre cloth.
NOTE:
Do not apply excess pressure to the cloth so as to avoid scratching the lenses.
To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass-cleaning solution and wipe the lenses gently. Protect the device from dust and moisture.
After use, particularly in high humidity, let the device acclimatize for a short period
of time, so that the residual moisture can dissipate before storing.
