About
The Hitachi HT7700 is a high contrast/high resolution digital transmission electron microscope (TEM). TEMs are able to image at a significantly higher resolution than a traditional light microscope.
This ability allows the user to examine very fine detail in their specimens (Ultrastructure). A user can clearly visualize characteristics of their specimens which are thousands of times smaller than the smallest resolvable object on a light microscope.
Transmission electron microscopy is an invaluable research tool for analysis in many scientific fields, both physical and biological. Our facility also offers sample preparation services.
