Making a permanently mounted slide of an insect wing
Topics: Making a dry mounted slide and one with mounting medium. Making a spacer ring with a slide ringing table. Here I show you how to prepare a wing of a wasp. The mounting medium used is Euparal, which is common for mounting insect specimens. In this video we will have a look at how […]
Cotton Candy under the microscope
Topics: watching cotton candy melt under the microscope. Cotton candy is pure sugar. It attracts moisture and this causes the cotton candy to melt. Under the microscope you can observe this process quite well.
Pollen from honey under the microscope
Extracting pollen from honey and observing it under the microscope. I will show you how to use a hand centrifuge to concentrate the pollen and how to make a temporary slide for observing them. Natural honey contains flower pollen. These pollen can be observed under the microscope, but you first have to concentrate them before […]
A slide ringing table for microscope slides and how to use it
Topics: Unpacking and checking the slide ringing table | making a dry-mounted slide. I ordered a slide ringing table from Brunel Microscopes (I am not affiliated with them). Here I have a closer look at this table and I am also making the first permanent slide with its help. These devices help in stabilizing the […]
Honey under the microscope
Polarized light microscopy to make sugar crystals visible in honey. Honey that is stored too cold might start to crystallize. The sugar crystals can be seen quite well using polarized light.
Volcanic sand under the microscope
Volcanic sand from the Canary Islands is observed with a stereo and compound microscope using top-illumination (epi-illumination). In this video I will show you how to make a permanent slide of sand and how I observed the sand using microscopy.
Which microscope head to buy? How many eyepieces?
Advantages of monocular, binocular and trinocular microscope heads. They differ in price and on comfort of use and photography. Monocular heads are the cheapest, small, light and do not have mechanical parts that might break. Binocular heads are good for long-term viewing and allow for the adjustment of eye distance and difference in eye-sight between […]
Dog under the microscope – well almost
How can you put dog specimens on a microscope slide without harming it? It’s surprisingly simple…
Example of a low quality microscope
Here I show you a microscope that has given me many (mostly mechanical) problems. There are even a range of design errors in the microscope.
