Yes, fixation of almost any kind can have effects on morphology. When you take a free flowing, protein spiked fat-blob (ie cell membrane), and make it rigid, you are going to get some differences. A fun visualization of this can be done by wrapping cellophane/shrink wrap around a serological pipette and dipping it in a dry ice and methanol bath. It's ...

Because you are looking at it from the top it would be helpful probably to have some phase on the scope to increase your contrast so that you can more ...

It sounds like you need a microscope for standard microbiology lab tests. At a minimum, any standard wide-field/brightfield microscope would work. If most of your histology work involves colorimetric stains (e.g., H&E, gram staining), you don't need any fluorescence capability. If you are working with a lower budget, look at the new lines of LED-based ...
