FEI Tecnai G2 20 TWIN Transmission Electron Microscope

Bionand’s FEI Tecnai G220 has been configured as a multi-task tool with emphasis on biological applications. To do so, Twin objective lens and the 4k x 4k Eagle ccd camera with high sensitivity (HS) scintillator show the emphasis made on optimizing contrast from biological samples. Other applications as Energy Dispersive Spectrometry (EDS) including a low background holder, cryo-TEM and Electron Tomography are also available.


  • Electron source with LaB6 emiter and flexible high tension between 20 and 200 kV.
  • Twin objective lens for high contrast and high tilt applications
  • Side-mounted CCD Olympus Veleta with 2k x 2k Mp, high field of view and fast read-out rates for real time observation.
  • Bottom mounted CCD FEI Eagle, 4k x 4k, HS scintillator.
  • EDS thanks to EDAX DPP-II analyzer with Si (Li) detector
  • Cryo-TEM
  • Electron tomography
  • Sample holders:
    • Single tilt
    • Low background (for EDS applications) double tilt
    • Fishione 2020 advanced tomography holder
    • Gatan 626 single tilt liquid nitrogen cryo transfer holder
    • Gatan 650 single tilt rotation analytical holder
