Observing Brownian motion
Brownian motion is the random movement of particles. This motion can be observed under the microscope, when looking at very small particles. In this case we will have a look at the fat droplets in milk.
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).
The importance of mounting medium refractive index
The refractive indes (RI) of the mounting medium can have a significant impact on the image quality.
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.
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.
