JSM5610LV SEM

Wet samples change character when dried, thus appearing different in the SEM compared to their native state. For porous samples, it is difficult to get the conductive coating into the subsurface spac-es. Charge build-up at the pores continues to interfere with the SEM examination. The variable vacuum mode in this SEM (1 to 270 Pa) allows imaging of samples containing moisture such as cells on bioglass substrates without the need for desiccation, and porous structures without the need for a conductive coating.

The images below show the porous structure of glass foam and the natural structure in a plant.
