Scanning Electron Microscope (SEM)

Camfil’s Scanning Electron Microscope (SEM), located at the laboratory in Trosa, is a great example of how committed we are to research and development. This unique tool allows us to study and identify contaminants as small as 50nm (=0,00005mm), found in used filters and air samples. The microscope is used as a problem solving and quality control capability for our customers, and also to study and evaluate new filter media.
