These microscopes have superior optical quality and better software, which interfaces with your PC or laptop via a USB cable. The phase contrast eliminates the need to stain for many (but not all) organisms.
Toni Glymph, a nationally-known Wastewater Microbiologist and author, approves of these microscopes and states:
“These microscopes are a great tool at an excellent price!"
It is impossible to specify the optical quality required with words. We guarantee that with these microscopes, you will not only see what you need to see, but also that you will be happy with the image quality, even at 1000x.
