White balance and image quality

During a recent walk through the forest, I collected some moss and continued to culture it on my desk on a shallow plate. Countless organisms could be found in the moss, and also the moss plant itself is quite suitable for microscopy. Figure 1 shows the original image, Figures 2 and 3 had white balance […]



High speed micrography – stinging nematocysts of a jelly fish

Maybe this is the reason why we do microscopy – “It’s the joy of actually coming and going: ‘I just saw something that nobody else has ever seen before.’”

Plasmolysis of red onion cells

Adding salt water to red onion cells will cause the cytoplasm to lose water by osmosis. The cell’s content shrinks.

What are the differences between aqueous and non-aqueous monting media?

Mounting media for microscopy can roughly be divided into those that are water soluble (aqueous) and those that are not (non-aqueous).

Red blood cells of human blood. No mounting medium used. Taken with 60x objective.

How to observe red blood cells

Red blood cells (also known as erythrocytes) are responsible for carrying oxygen from the lungs to the rest of the body. Unlike other cells, red blood cells do not have a nucleus (they have lost it during development). The available space can now be used to carry hemoglobin, the red pigment which carries oxygen. The […]



Glass bulb

Why should you never touch the bulb of a microscope lamp?

Microscope bulbs should never be touched with bare hands, as the grease deposited on the lamp will cause its breakage.



Dry-mounted slide

How do you make dry-mounted permanent slides?

Dry-mounted permanent slides do not use a mounting medium. It is necessary to hold the cover glass in place using adhesive tape.

This parasite is spread over the tsetse fly and causes the sleeping sickness.



Blue daylight filter

What are the advantages of using a blue filter for microscopy?

A blue daylight filter is able to remove red parts of the color spectrum when using tungsten or halogen lamps, giving the micrograph a cooler color.
