Moldy bread. But the spores look nice.
Here I put some mold under the microscope. The spores are visible in bright field as well as in phase contrast. I also look at it using my stereo microscope.
Synthetic fibers look great!
Some fibers in brightfield and darkfield. The fibers have a diameter of about 0.015mm. They are thinner than the cells of some algae. At the end of the video, I superimpose the images of the algae and the fibers to allow for a direct comparison.
Sad: Paramecium squashed to death, organelles spilling out
Pretty sad. 🙁 The ciliate paramecium was squashed to death between the microscope slide and cover glass….
How to view stomata under the microscope
This is a very simple, yet effective way of making cell surfaces visible. Here I am making a glue impression of a leaf surface. The stomata are visible under the microscope.
Why you can not identify bacteria with a microscope alone
The shape of bacteria reveals very little about what type of bacteria they are.
Phase Contrast Microscopy – all you ever wanted to know
Phase contrast microscopy allows you to see transparent and unstained specimens much better. The microscope converts differences in refractive index to differences in brightness.
Fly larvae (maggots) under the microscope
Maggots are fly larvae. They will form flies after metamorphosis. The flies then produce eggs, out of which more fly larvae emerge.
DIY Slide Ringing Table
A cheap slide ringing table can be made by mounting a CD on a fidget spinner. How to use a slide ringing table: https://youtu.be/0Gh7DJG-9aw
Red blood cells under the microscope
Topic: Looking at blood with bright field, dark field and phase contrast. You can see the red blood cells (erythrocytes) quite well. I bumped my head on the corner of the car door unloading some shopping.
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 […]
