Location, connection type

Before setting up your microscope, choose a suitable location.
First, make sure that your microscope is set up on a stable, vibration-free surface.

ATTENTION!
Always use the supplied mains adapter (5V, 1A) for this microscope.
Using an unsuitable power supply unit can cause damage to the microscope!

A mains connection (220-230 V) is required for making observations on the LCD monitor with the electric LED light.
Furthermore, the microscope has a USB interface (Fig.2, 1B). This enables the data to be transferred from the memory card to your computer (the memory card functions as an external memory).

Start-up

Connect microscope

Check that the lighting selector switch ( Fig. 1, 19 ) is in the “OFF” position before use.

To switch on the microscope, connect the supplied mains adapter (Fig. 5, 38 (5V, 1A)) with the mains connection (Fig. 1, 17) on the back of the microscope base (Fig. 1, 10), and then plug the mains plug into a suitable socket (220-230 V).

Adjusting the illumination

There are three different light modes

The microscope is equipped with two LED lights. There are three different light modes. On the illumination selector switch (Fig. 1, 19), select position I to illuminate the specimen from below (transmitted light) or position II to illuminate it from above (incident light). Select position “III” to illuminate the specimen from above and below at the same time. The transmitted light unit (Fig. 1, 9) is designed for transparent specimens (specimens on slides). To view solid, opaque objects, select the upper illumination unit (incident light) (Fig. 1, 13) The upper illumination unit is only useful when using the 4x lens.
The simultaneous use of both illuminators is only advisable for semi- transparent objects. This mode is not recommended for transmitted light microscopy on slides, as this can lead to reflections on the slides.
If the selector switch (Fig. 1, 19) is in the OFF position, the lighting is switched off.

Dimmer

The microscope is equipped with an adjustable illumination (dimmer) (Fig. 1, 18).
This allows you to adjust the brightness of the object to ensure optimal illumination.

ATTENTION!
The i mage brightness on the LCD monitor does NOT change by turning the dimmer dial. You can adjust the image brightness separately on the LCD monitor (section 3.2.1.d)

Switch on the LCD monitor

Switch on the LCD monitor (Fig. 1+2, 2) on by PUSHING the on/off switch for AT LEAST 3 SECONDS (Fig. 1+2, 12). The operating light (Fig. 1+2, 11) lights up green briefly. The writing appears on the screen: “Insert a SD Memory Card” (A suitable SD memory card (max. 32GB) into the SD card slot (Fig.2, 1A).
Slide the rubber cover (protection against dirt) on the left side of the LCD monitor to the side and insert a suitable SD memory card into the SD card slot (Fig.2, 1A).

ATTENTION!
To store the recordings, an SD memory card is required (max. 32GB) Optional (not included)

OBSERVATION

General information on
microscope observation
Once you have assembled the microscope and set the required light mode, the following principles apply:

a) Start each observation session with the lowest magnification – this will make it easier to centre and position your specimen.
Move the microscope stage (Fig. 1, 7) with the focusing wheel (Fig. 1, 16) all the way down and then turn the nosepiece (Fig. 1, 4) until it is locked at the lowest magnification (the 4x objective is vertical).
b) Start with a simple observation. Place a permanent specimen (Fig. 1+3, 6) directly under the objective on the microscope stage (Fig. 1+3, 7) by clamping it in the XY stage (Fig. 1+3, 14). To do this, move the lever for the clamp (Fig. 3, 28) to the side, place the permanent specimen on the stage and release the clamp (Fig. 3, 29) carefully to hold the permanent slide in place. The object which is to be observed must be exactly above or below the illumination. Use the two knurled screws on the stage to adjust the position of the specimen. These are the so-called cross table drives (Fig. 3, 26+27).
By turning these screws, the object can be moved precisely to the left or right (Fig. 3, 27) as well as forwards or backwards (Fig. 3, 26).
c) Look at the LCD monitor (Fig. 1+2, 2) and carefully turn the focus wheel (Fig. 1, 16) until the image is sharp. You can now use the XY stage to centre the specimen at the desired position on the LCD monitor.
d) For a higher magnification, turn the nosepiece (Fig. 1, 4) until the 10x or 40x objectives click into place.

ATTENTION!
Before changing the objective setting, move the microscope stage (Fig. 1, 7) all the way down. to avoid damaging the microscope.

The higher the magnification, the more light is needed to obtain a good image.

IMPORTANT NOTE:

Depending on the preparation in use, higher magnification will not always lead to a better picture! The magnification is changed by changing the objective.
This changes the sharpness of the image, which must then be adjusted with the focus wheel (Fig. 1, 16) must be readjusted. Be very careful when doing this. If you raise the microscope table too quickly, the objective and the slides can touch each other and be damaged!
e) The magnification factor of the LCD modules corresponds to 12.5x. In combination with the 4x-objective we obtain a total magnification of 40x, i.e. 1 mm of the object is shown as 40 mm on the LCD monitor.The total magnification is 125x with the 10x lens, and 500x with the 40x lens, respectively.
f) The color filter disc (Fig. 1+4, 15) under the microscope stage (Fig. 1+4, 7) is useful for viewing very bright or transparent specimens. If you wish to use the color filter disc,
select the appropriate color for your specimen. The color filter disc makes the components of colorless or transparent objects (e.g. starch grain, single- celled organisms) much easier to recognize.

LCD Monitor

Observations on the LCD monitor

If you switch on the LCD monitor (see section 2.3), you will see the live image of your object as well as five different icons:

a) The camera icon (photo mode) along with the SD card storage capacity is displayed on the top left of the LCD monitor.

Image output and image storage

ATTENTION!
SD card (max. 32 GB) required (not included).

The LCD student microscope offers the possibility to display and save images:
a) Choose the best settings so your object is visible on the LCD monitor (Fig. 1+2.2).
b) You can store your photographs on a suitable SD memory card*. The SD card slot

(Fig. 2, 1 A) is located on the left side of the monitor (Fig. 2, 2) over the mini-USB port (Fig. 2, 1B). Slide the SD card into the card slot with the contacts facing the user until it clicks into place. When a memory card is inserted, a blue memory card symbol will appear at the top of the LCD monitor. To remove the card, press gently on the back of the card. After you here a click, it can be released from the slot. Your photos can now be transported and used in other devices.
c) If you connect your microscope to the PC with the supplied USB cable (Fig. 5, 32), you can transfer the previously recorded data to the PC.
NOTE:
No live image is transmitted to the PC.
WARNING: A SD memory card (max. 32 GB) must be plugged in!
The mini-USB port is located on the left side of the LCD monitor (Fig. 2.1 B) below the card slot. Insert the smaller USB 2.0 mini connector (type B) (Fig. 5, 32/1) into the socket on the microscope, and then insert the larger Type-A plug (Fig. 5, 32/2) into a free USB port on your computer. After successful USB connection, the operating system detects new hardware and initializes a new drive.
This drive will be labelled as “Removable Disk E:” or “Removable Disk F:”. The letters vary depending on the number of drives connected to your computer and are visible in Windows Explorer. This drive contains the contents of your SD memory card.

PLEASE NOTE:

The error message Access SD card error! after removing the card is answered by pressing the OK button.
If the card contains very large amounts of data, the microscope may become very slow or stop responding (“crash”). If this occurs, remove the card, switch off the microscope, wait for approx. 5 seconds, and then switch it back on again.
When completely deleting very large amounts of data with the MENU Delete File All selection, not all files may be deleted the first time. If this is the case, repeat the step until the memory card is completely empty.

ATTENTION!
During exposures, it is not possible to establish a PC connection at the same time. Before interrupting a USB connection or switching off the microscope, make sure that the SD card is deactivated. If this is not thecae, disconnect the mass storage drive in Windows Explorer! If the drive is not disabled properly, your computer may crash or data on the card could be lost!

NOTE:
We recommend using SD memory cards
with a capacity of up to 32 GB.

Observation object – texture and preparation

Texture
This microscope, which is both an incident and transmitted light model, can be used to examine transparent and non-transparent samples. When examining opaque objects – such as small animals, plants, textile, minerals – light is reflected from the specimen through the lens and eyepiece, where it is magnified, into the eye (incident light principle, illumination selector switch (Fig. 1, 19) – position I). For transparent specimens, the light passes from below through the specimen, lens and digital eyepiece to your eye and is magnified on the way (transmitted light microscopy, switch position II). Many small water organisms, plant parts and tiny animal matter are naturally transparent, while others have to be prepared accordingly. Either transparency is achieved by pretreatment or penetration with suitable materials (media) or very thin cuts are made by hand using the Micro Cut (Fig. 5, 36) made, which are subsequently used for the observation. These methods will be explained in more detail in the next section.

Making thin sections
The specimens should be cut as thin as possible. A small amount of wax or paraffin is needed to achieve the best results. For this purpose, you can use a candle. The wax is placed in a metal bowl and heated over a flame. Dip the specimen several times into the liquid wax, and then leave it to harden.
Use a Micro Cut (Fig. 5, 36) or a knife/scalpel (CAUTION: sharp-edged) to make very thin cuts from the object embedded in wax. These sections are then placed on a slide and covered with a coverslip.

Making your own preparations
Place the specimen on a slide and use a pipette (Fig. 5, 34 B) to place a drop of distilled water on the specimen (Fig. 6).
Place a coverslip upright on the edge of the water drop so that the water runs along the edge of the coverslip (Fig. 7). Slowly lower the coverslip onto the drop of water.

NOTE:
The supplied Gum-Media (special adhesive) (Fig. 5, 37 B) is used for the production of permanent preparations.
Add it instead of distilled water. The gum medium hardens so that the specimen is permanently affixed to its slide.

EXPERIMENTS

If you are already familiar with the microscope, you can carry out the following experiments and observe the results under your microscope.

Newspaper print

A small clipping from a newspaper containing part of a picture and some letters.
A similar piece of paper from an illustrated magazine. Place the piece from the newspaper on the microscope stage and set the lowest magnification on the objective nosepiece. The letters look frayed and broken because the daily newspaper is printed on rough, relatively low-quality paper. The image on the newspaper clipping consists of many small dots that appear somewhat pixelated.
In comparison, the letters of the illustrated magazine appear smoother and more complete. The image dots (pixels) stand out sharply here.

Textile fibers

Objects and accessories:

Threads of various textiles: Cotton, linen, wool, silk, Celanese (cellulose based synthetic fiber), nylon etc..
Two dissecting needles (Fig. 5.34A).
Each thread is placed on a slide and frayed using the two dissecting needles. The threads are moistened and covered with a coverslip. The microscope is set to a low magnification at the nosepiece.
Cotton fibers are of plant origin and look like a flat, twisted ribbon under the microscope.
The fibers are thicker and rounder at the edges than in the middle. Cotton fibers consist mainly of long, collapsed tubes.
Linen fibers are also of plant origin. They are round and run in a straight line. The fibers shine like silk and appear to have countless swellings on the fiber tube.
Silk is of animal origin and, unlike the hollow plant fibers, consists of solid fibers with a smaller diameter. Each fiber is smooth and even and looks like a small glass rod.
Wool fibers are also of animal origin. The surface consists of overlapping sleeves that appear broken and wavy. If possible, compare wool fibers from different weaving mills. Note the different appearance of the fibers. Experts can use this information to determine the wool’s country of origin.
Celanese, as the name suggests, is produced artificially through a lengthy chemical process. All fibers have hard, dark lines on the smooth, shiny surface. The fibers curl up in the same way after drying. Compare and observe similarities and differences.

Brine shrimp for breeding and long-term observation
Accessories:

Shallow vessel with approx. 2-3 L volume (canning jar, glass bowl, mini aquarium
or Fauna box) – to ensure sufficient air exchange at the water surface.\
2-3 liters of rainwater, Vulvic(or other non carbonated mineral water)
permanent eggs of the brine shrimp (Fig. 5, 37D)
Sea salt (preferably unpurified, without additives, apt. 100g)
Note: the supplied amount of sea salt (Fig.
37C) is not sufficient for this long-term experiment!
Dry yeast (Fig. 5, 37A) – food
Pipette (Fig. 5, 34B) or a thin tube – to remove animals or change water.
Brine shrimp hatchery (Fig. 5, 35) – to observe the animals under the microscope or to hatch only a few naupliar (not recommended as it is not possible to keep them for longer in this vessel).
Optional: Baking soda (not: baking powder) (approx. 5

The life cycle of the brine shrimp
The brine shrimp, or Arteria saline, has an unusual and interesting life cycle which is a topic of ongoing research. The eggs of the female hatch without the need for male shrimp to fertilize them. The resulting baby brine shrimp are all female. Under unusual circumstances, such as when a marsh is drained, the eggs may produce male shrimp. These males fertilize the eggs of the females, resulting in a certain type of egg. These eggs, called “permanent eggs” or cysts, have a thick shell that protects the egg. The “winter eggs” are very resilient and remain viable even if the marsh or lake dries up, causing the death of the entire brine shrimp population. They can remain in a “dormant” state for 5-10 years. The eggs hatch as soon as the right environmental conditions prevail again. The provided brine shrimp eggs are of this nature.

Rearing of brine shrimp
In order to hatch, rear and observe the shrimp for a longer period of time, portent to first prepare a large batch of saline solution that corresponds to the living conditions of the shrimp.
You will need a vessel for about 2-3 L (canning jar, glass bowl, mini aquarium or Fauna box). For the preparation it is best to use a rather shallow vessel to ensure sufficient air exchange at the water surface.
The permanent eggs you put 2-3 liters of rainwater. Add one tablespoon (about 10-15 g) of sea salt without additives per 0.5 L to the water. Unpurified, gray sea salt is optimal. To make the pH slightly alkaline (pH about 7.5-8.0), a pinch of sodium bicarbonate (baking soda) can be added per 0.5 L. If the water is chlorinated or contains copper (e.g. from pipes, water heaters), you can use mineral waters low in minerals and neutral in pH (e.g. Vulvic) for the preparation, as invertebrates are very sensitive to chlorine and heavy metals. The container should be at room temperature, bright, but not in direct sunlight.
After 24-48 hours at room temperature, the first 0.3 mm to 0.5 mm baby shrimp, called Nauplius, hatch. These paddle through the water with the pair of rudder antennas.
Initially, the Arteria molt at very short intervals (a few hours). Only after several molts the number of leg pairs increases. Depending on the ambient temperature, the shrimp are fully grown in 6 to 10 weeks. They will soon have bred a whole generation of brine shrimp that are constantly reproducing.

Brine shrimp under the microscope
The animals can be optimally observed with a reflected light microscope. To do this, add a few animals to some water in the hatchery tank. Smaller animals can also be pipetted with a pipette with the largest possible opening or aspirated with a thin tube.
You can remove the lid of the hatchery and view it in its entirety under the microscope.
During microscopy, the specimen may heat up due to the microscope illumination. Important: Keep observation times short.
During breaks, turn off the lights, and take down the saltwater crayfish hatchery with the animals from the microscope! After observation, quickly return the animals to the culture vessel.

Feeding and water change
To keep them alive, brine shrimp must be fed occasionally. This should be done carefully, otherwise the water will spoil and the crayfish will be poisoned. Feeding is best done with dry yeast powder (Fig. 5, 37A), spirulina powder or “green water”. Give the shrimp a little bit of food from the 2nd day day on after hatching, and then feed a little bit every other day. To preserve the culture for as long as possible, you can use a pipette to siphon off any detritus and leftover food from the bottom. Evaporated water is topped up with deionized or distilled water.
Every two weeks you should also replace part of the water. It is important that the water change is done carefully; the fresh water should have the same temperature and composition, and added over a period of at least 1-2 hours. With a little luck, this allows the culture to be maintained for a period of up to 6 months (max. age of brine shrimp). On the bottom you might be able to find new cysts that can be dried. From these cysts you can hatch a new generation.

ATTENTION!
BRINE SHRIMP AND THEIR EGGS ARE NOT SUITABLE FOR CONSUMPTION!
