Tecnai 20 - FEI 200kV Twin Lens (STEM)

Our FEI Tecnai 20 200 kV Twin lens TEM is optimised for cryo-EM, electron tomography, TEM and STEM experiments.

It is suitable for other applications requiring high resolution imaging or analysis of thick sections.

Special features:

Availability of cryo equipment including rapid freezing equipment for preparing samples and Gatan cryo-transfer holder, FEI cold box and Low Dose and EPU software for analysis on the microscope.
LaB6 filament for improved resolution and brightness.
FEI Ceta 4k x 4k CCD camera as well as a plate camera.
HAADF (high angle annular darkfield) scanning transmission electron microscopy (STEM) detector for high contrast imaging of high atomic number elements (gold, quantum dots in biological samples).
Twin lens system with improved aberration correction (spherical and chromatic; Cs and Cc).
Generation of 3D tomographic data from thick samples is enabled by collection of tilt series images between -70° and +70° using a dedicated Fischione tomography holder. Dedicated FEI software enables acquisition of electron tomography data in TEM and STEM modes.
