We have a Philips Tecnai F20 for the characterization of samples at higher resolution, which is equipped with a field-emission cathode (FEG) that can be operated at a maximum accelerating voltage of 200 kV. Image recording is performed with an Eagle 4k CCD camera. The high sensitivity of the CCD camera can record tomographic image series even for cryo-fixated samples. Corresponding control and evaluation software (TIA, Inspect 3D) is also at hand. For cryo-TEM investigations two Gatan cryo-transfer systems (cryoholder and –stage, model 626; tomography holder and stage, model 914) are available.
