Transmission Electron Microscopes
JEOL JEM-2200FS with 2x CS correctors
The JEM-2200FS combines a 200 kV field emission gun (FEG) and in in-column energy filter (Omega Filter) to produce a high-end, optimally configured TEM for energy filtered imagery.
JEOL JEM-3200FSC Liquid Helium Cryo-TEM
Ideally suited for imaging low contrast, frozen biological samples, the JEM-3200FSC field emission cryo-TEM is equipped with an in-column Omega-type energy filter spectrometer.
FEI Tecnai 12 Bio Twin TEM
120 kV TEM especially for soft-matter analysis.
