Experiments collection

On this page you will find some sample experiments to familiarise yourself with microscopy.

Have you just bought a Bresser microscope? I would now like to give you a few tips to help you gain a better insight into the wonderful world of microorganisms and crystals. For example, I will explain how to prepare objects so that you can view them with a microscope. The many experiments described should make you curious to continue observing with the microscope.

CAUTION
  • Chemicals and corrosive liquids do not belong in the hands of children!
  • Do not drink any chemicals!
  • Clean hands thoroughly under running water after use!

How the object must be designed

You can use a magnifying glass to observe opaque objects, e.g. small animals, parts of plants, tissue, etc.. The light falls on the object to be observed, is reflected back from there and enters the eye through the magnifying lens.

However, you can use your microscope to examine transparent objects where the light from the mirror or light bulb shines through the opening of the specimen stage onto the specimen from below. From there it passes through the objective, the tube and then through the eyepiece of the microscope into your eye. This leads us to the conclusion that only transparent objects are suitable for examination with a microscope. Many small aquatic organisms, parts of plants and the finest animal components are transparent by nature, while others must first be given this property. We can make them transparent by pretreating them or penetrating them with suitable substances (media) or by cutting very fine slices from them (hand section, thin section) and then examining them. You can now find out how these methods are used.

How to make thin specimen sections

CAUTION: Please only do this under the supervision of an adult! Ask your parents to help you! Here you will find microscope accessories for carrying out these experiments.

As I said before, you need to make the thinnest possible sections of an object so that they become transparent and can be observed with a microscope. Firstly, you need a simple candle. Put the wax from the candle in an old pot and heat it on the cooker until it has become liquid. Now dip the object into the liquid wax several times using tweezers.

CAUTION: The wax is very hot! Be careful!

After each dip, allow it to harden and then dip it again. When the wax around the object has completely hardened, you can make very fine sections of the object using the thin sectioning tool or a scalpel. These sections are placed on a microscope slide and covered with a cover glass.

The manufacture of preparations

There are two basic types of preparations. Permanent preparations and preparations with a limited shelf life.

Temporary specimens are made from objects that you want to observe but do not want to include in your specimen collection. These preparations are only suitable for observation for a short time and are then destroyed. For time-limited preparations, place the object on a microscope slide with a cover glass over it. After observation, the slide and cover glass are cleaned. One of the secrets of good observation with a microscope is the use of clean slides and clean cover glasses. Stains would only interfere with observation.

Permanent preparations (e.g. of animals) are made of objects that have turned out particularly well and that you want to observe again and again. The preparation of dry objects (pollen, wings of a fly, etc.) can only be done with a special adhesive. You will also find such an adhesive in your accessory set under the name ‘Gum-Media’. Objects that contain moisture must first have the moisture removed.

csm_5201001_A2_5be2ab50da.jpg

How to prepare a dry object

First place the object in the centre of a clean microscope slide and cover it with a drop of glue (Gum-Media). Then place a cover glass on the object enclosed by the chemical. Press the cover glass lightly so that the glue spreads to the ends of the cover glass. You must now leave the preparation to harden for 2-3 days. Only then is the preparation really firmly bonded and you can use it.

Lubricating preparations

For a smear preparation, use the pipette to place a drop of the liquid to be observed (e.g. water from a puddle on a forest path) on one end of the slide. You can then spread the liquid using a second slide. Allow the substance to dry for a few minutes before observing.

Experiments

Objects:

  1. a small piece of paper from a daily newspaper with part of a black and white picture and a few letters
  2. a similar piece of paper from a magazine.

In order to be able to observe the letters and the images, you make a time-limited preparation of each object. Now set your microscope to the lowest magnification and use the preparation with the newspaper. The letters look frayed and broken because the daily newspaper is printed on rough, low-quality paper. Letters in the magazine appear smoother and more complete. The image of the daily newspaper consists of many small dots that appear somewhat dirty. The image dots (halftone dots) of the illustrated newspaper image are sharply defined.

Objects:

  1. a small piece of colourful printed newspaper,
  2. a similar piece of paper from a magazine.

Time-limited preparations are made of the objects and observed at the lowest magnification. The coloured pixels of the daily newspaper often overlap. Sometimes you can even see two colours on one dot. When looking at the coloured image of the magazine, the dots appear sharp and rich in contrast. Note the different sizes of the pixels.

Objects and accessories:

  1. Threads from various textiles (e.g. cotton, linen, wool, silk, artificial silk, nylon, etc.)
  2. two needles

Each thread is placed on a glass slide and defibred with the help of the needles. The threads are moistened and covered with a cover slip. The microscope is set to a low magnification. Cotton fibres are of plant origin and look like a flat, twisted ribbon under the microscope. The fibres are thicker and rounder at the edges than in the middle. Cotton fibres are basically long, collapsed tubes. Linen fibres are also of plant origin, they are round and run in a straight direction. The fibres shine like silk and have countless swellings on the fibre tube. Silk is of animal origin and consists of solid fibres of smaller diameter in contrast to the hollow plant fibres. Each 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 sheaths that appear broken and wavy. If possible, compare wool fibres from different weaving mills. Note the different appearance of the fibres. Experts can determine the country of origin of the wool from this. Artificial silk is, as the name suggests, man-made through a long chemical process. All fibres show hard, dark lines on the smooth, shiny surface. The fibres curl after drying in the same condition. Observe the similarities and differences.

Objekts:
gewöhnliches Tafelsalz.

Zuerst gibst Du einige Körnchen Salz auf einen Glas-Objektträger und beobachtest die Salzkristalle mit der niedrigsten Vergrößerung Deines Mikroskops. Die Kristalle sind kleine Würfel und sind in der Form alle gleich.

Object and accessories:

  1. Table salt ,
  2. Test tube half-filled with hot water,
  3. Cotton thread,
  4. Paper clip,
  5. Match or pencil.

Add enough salt to the water until it no longer dissolves. We have now obtained a saturated salt solution. Wait until the water has cooled down. Attach the paper clip to one end of the cotton thread and use it as a weight. Tie the other end of the cotton thread into a bow, stick the match through it and dip the whole thing into the salt solution. The match is placed horizontally over the opening of the test tube and prevents the cotton thread from slipping into the test tube. The jar is now placed in a warm place in the home for 3-4 days. If we look at the glass again after a few days, we will see that a whole colony of salt crystals has formed on the cotton thread.

Accessories (from your Mikrokop set):
  1. Prawn eggs,
  2. Sea salt
  3. Gross bank
  4. Yeast.

The life cycle of the saltwater shrimp The saltwater shrimp or ‘Artemia salina’, as it is called by scientists, goes through an unusual and interesting life cycle. The eggs produced by the females are hatched without ever having been fertilised by a male shrimp. The shrimps hatched from these eggs are all females. Under unusual circumstances, e.g. when the swamp dries out, male shrimps can hatch from the eggs. These males fertilise the eggs of the females and the mating results in special eggs. These eggs, known as ‘winter eggs’, have a thick shell that protects the egg. The winter eggs are very resilient and remain viable even if the swamp or lake dries up, causing the death of the entire shrimp population. They can remain in a ‘dormant’ state for 5-10 years. The eggs hatch when the right environmental conditions are restored. You will find such eggs in your microscope set.

Hatching the saltwater shrimp
To hatch the shrimp, it is first necessary to prepare a salt solution that corresponds to the living conditions of the shrimp. To do this, pour half a litre of rain or tap water into a container. Leave this water to stand for approx. 30 hours. As the water evaporates over time, it is advisable to fill a second container with water and leave it to stand for 36 hours. After the water has ‘stood’ for this time, pour half of the added sea salt into the container and stir until the salt has completely dissolved. Now add a few eggs to the jar and cover with a plate. Place the jar in a bright place, but avoid exposing the container to direct sunlight. As you have a gross tank at your disposal, you can also add the salt solution with some eggs to each of the four cells of the tank. The temperature should be approx. 25° C. At this temperature, the shrimp will hatch after about 2-3 days. If the water in the tank evaporates during this time, top up with water from the second tank.

The saltwater shrimp under the microscope
Das Tier, das aus dem Ei schlüpft, ist bekannt unter dem Namen „Nauplius-Larve“. Mit Hilfe der Pipette kannst Du einige dieser Larven auf einen Glas-Objektträger legen und beobachten. Die Larve wird sich durch das Salzwasser mit Hilfe ihrer haarähnlichen Auswüchse bewegen. Entnehme jeden Tag einige Larven aus dem Gefäß und beobachte sie unter dem Mikroskop. Falls Du die Larven in einem Bruttank gezogen hast, nimm einfach die obere Kappe des Tanks ab und setze den Tank auf den Objekttisch.
Abhängig von der Raumtemperatur wird die Larve innerhalb von 6-10 Wochen ausgereift sein. Bald wirst Du eine ganze Generation von Salzwasser-Garnelen gezüchtet haben, die sich immer wieder vermehrt. 
Das Füttern Deiner Salzwasser-Garnelen
Um die Salzwasser-Garnelen am Leben zu erhalten, müssen sie natürlich von Zeit zu Zeit gefüttert werden. Dies muss sorgfältig geschehen, da eine Überfütterung bewirkt, dass das Wasser fault und unsere Garnelen-Bevölkerung vergiftet wird. Die Fütterung erfolgt am besten mit trockener Hefe in Pulverform. Ein wenig von dieser Hefe jeden zweiten Tag genügt. Wenn das Wasser in den Kästchen des Bruttanks oder in Deinem Behälter dunkel wird, ist das ein Zeichen, dass es fault. Nimm die Garnelen dann sofort aus dem Wasser und setze sie in eine frische Salz-Lösung. 
CAUTION! The shrimp eggs and shrimp are not suitable for consumption!

BRESSER DST-0745 Ultra Macro Zoom Microscope
BRESSER DST-0745 Ultra Macro Zoom Microscope
The BRESSER DST-0745 is a special microscope that is operated with a c-mount camera (camera not included). This allows direct viewing on a screen. Due to the vertically installed optics, there is no shifting of the image when focusing. This is especially useful for "focus stacking" shots. The zoom is continuously adjustable from 0.7x - 4.5x. A coarse and fine focus adjustment facilitates focusing, especially at high magnifications. The convenient and user-friendly operation makes the digital microscope particularly suitable for daily use in the workshop. Measurements, quality control of surfaces or inspection of components and raw materials are easy with the workshop microscope. Insects, plants and rocks are also impressively displayed. The DST-0745 workshop microscope is not suitable for visual observation. It can only be used in combination with a MikroCam c-mount microscope camera. It is designed for camera sensors of about 1/2". Smaller sensors can be used without problems. With larger sensors there is vignetting, which becomes somewhat less at higher magnifications. Due to the two flexible incident light lamps, the light can be optimally positioned. The transmitted light illumination helps when observing transparent objects. The brightness of both illuminators can be adjusted in five steps. The magnification of a USB camera differs from the magnification of the lens. It depends, among other things, on the sensor size and the display on a monitor. It can be compared to macro lenses with macro factor 0.7:1 up to 4.5:1.

Nexcope NIB630 inverted research microscope with tiltable lighting unit
Nexcope NIB630 inverted research microscope with tiltable lighting unit
The NIB 630 is the flagship of the NIB600 series of inverted microscopes. With such an inverted design, the device enables the microscopy of plankton, microalgae and cell cultures. Cell cultures can be examined directly in the culture vessel without taking samples. For particularly easy sample handling, it is equipped with a tiltable lighting unit. This means that even tall vessels can be placed comfortably without bumping against the lighting unit. The microscope head is equipped with a height-adjustable ergo viewing head. This allows users of different heights to adjust the microscope to a comfortable and ergonomic viewing height with a single hand movement. This special microscope is used in water management offices, research institutes and universities, in human and veterinary medicine, agriculture, marine biology, limnology, aquaculture and many more. The integrated display informs you at any time about the selected magnification and the status of the illumination as well as the ECO mode. The brightness can be programmed for each objective so that there is no need to readjust when changing magnification and the user is not blinded. OBJECTIVE The NEXCOPE NIB630 microscope is equipped with a quintuple nosepiece. A 4x planachromatic objective and one each of 10x, 20x and 40x planachromatic phase contrast objectives are included. The condenser has a numerical aperture of 0.3 and an extra long working distance. The objectives are calculated for a soil thickness of 1.2 mm. Please use appropriate culture vessels. The universal specimen holder is suitable for standard slides. EYEPIECES The eyepieces have a field of view of 22 mm. This gives you a very large field of view. The high eye point makes them very comfortable even for spectacle wearers. A rubber edge protects against scratches on contact. Dioptric compensation from -5 to +5 can be individually adjusted for each eyepiece. The interpupillary distance can be adjusted between 48 mm and 75 mm. The binocular can be tilted up and down to adjust the viewing height. ILLUMINATION The Koehler illumination provides the best possible light guidance of the microscopy light. This avoids stray light and only illuminates the just visible area in the specimen. This protects sensitive living specimens from excessive light irradiation. The powerful 3W LED can be adjusted in brightness and ensures optimal illumination. The brightness can be adjusted individually for each objective. If an objective is changed, the NEXCOPE NIB630 automatically adjusts the previously set brightness. The display shows the currently selected lens and the current brightness. The tiltable lighting unit makes it easier to work with taller sample vessels. The adjustable condenser with extra-long working distance enables quick readiness for use. MECHANICS In addition to coarse focusing, fine focusing helps to bring the specimen into focus very precisely. A full turn of the fine focusing knob moves the stage up or down by 0.2 mm. On the right side, the fine focus can be adjusted with a finger. The friction of the coarse focusing can also be varied. The fine focusing knobs are held magnetically and can be mounted on the left or right. The XY stage offers the possibility of inserting various holders. This allows slides or even petri dishes to be inserted. CAMERA CONNECTION The NEXCOPE NIB630 is specially designed for use with C-mount cameras. The camera connection is located on the side and has a switch between visual observation and camera (100/0 or 0/100). You can choose from two different adapters, depending on the sensor size: 0.5x C-mount adapter 1x C-mount adapter (already included in the scope of delivery) ACCESSORIES (optional) Hoffman Modulation Contrast Relief 3D contrast Terasaki holder, Petri dish holder 54 mm and 90 mm Camera adapter for C-mount 0.5x FEATURES Professional inverted transmitted light microscope Type of objectives: infinity plan achromatic (60 mm adjustment length, M25) Precise mechanics Very bright illumination SCOPE OF DELIVERY Inverted transmitted light microscope 4x objectives, of which 10x, 20x and 40x as phase contrast objectives Filter slider for phase contrast Universal sample holder Centering telescope for phase contrast
