Setting up a Home Laboratory for Microscopy
The home laboratory provides a safe working environment for microscopic investigations.
Determining Size in Microscopic Images
Here is an instruction on how to calculate the size of cells using a microscope.
How to prevent Air Bubbles in Wet Mounts
There are several methods how bubbles can be reduced when making slides.
Testing the Hand Microtome
Cutting a carrot with a hand microtome.
Making a wet mount microscope slide
This post explains how to make a wet mount. Video included!
Fixing specimens for making permanent slides
Before specimens can be processed for making permanent slides, they may need to be fixed.
The hemocytometer (counting chamber)
A hemocytometer or counting chamber is used to count cell density. Here I show you how this is done.
How to obtain the best resolution with your microscope
The resolution that a microscope is capable of achieving is probably the single most important factor that determines the quality of a microscopic image. Without a sufficiently high resolution, magnification is not possible without loss of quality. There are a variety of different factors that determine the achievable resolution. Some of these factors can not be actively influenced by the microscopist, others can. Some of the factors play a larger role, others a smaller one. In the following post, I want to summarize some of these factors.
Cover glass thickness and resolution
The thickness of the cover glass can have a significant impact on the resolution.
Köhler illumination to reduce reflections
Köhler illumination reduces stray light and therefore increases contrast when taking pictures.
