Instruments Available:

Titan Krios - 300kV high-end transmission electron microscope aligned for fringe free imaging (FFI) and equipped with Volta phase plate (VPP), Falcon 3EC direct electron camera, energy filter with K3 direct electron detector (Bioquantum 1067). The microscope serves for high throughput and high-quality single particle analysis and cryo-electron tomography data collection.

Glacios 2 is a 200kV (scanning-)transmission electron microscope for life-science applications. The microscope is equipped with a Falcon 4i direct electron detector for TEM applications, a Ceta-D camera for electron diffraction tomography, and a set of bright-field, dark-field and high angle annular dark-field detectors (Panther STEM, ThermoScientific) for STEM imaging. Data acquisition can be automated using SerialEM, EPU Multigrid and Tomo5 (including Tomo-Live for real-time tomogram reconstruction).

Helios Hydra pFIB/SEM is a plasma-FIB/SEM dual beam microscopes for room temperature and cryo-electron microscopy applications. High-resolution scanning electron microscope (Elstar column) with capacity for imaging in immersion mode and attainable resolution of 0.6nm. The signal can be detected using in-chamber ETD, ICE, retractable DBS detectors, or in-column TLD and ICD detectors. FIB column with Xe, Ar, O, and N plasma. The microscope is further equipped with cryo-stage and cryo-transfer accessories, a micromanipulator for lift-out under room-temperature and cryo-conditions, and an integrated wide-field flourescence microscope.

Talos Arctica – 200 kV high-end transmission electron microscope equipped with Ceta camera, Falcon 3EC direct electron detector, and post-GIF K2 direct electron detector (Bioquantum 967). The microscope serves for acquisition of single particle analysis data, high-throughput screening of cryo-EM samples, and acquisition of electron diffraction tomography (microED) data.

Talos F200C  - 200kV scanning transmission electron microscope for operation in both TEM and STEM modes. The microscope is equipped with Falcon 3EC direct electron detector, Ceta-D camera, and Quadro (Dectris) direct electron detection camera. In addition, the microscope is equipped with HAADF detector for imaging in STEM and Bruker X-flash detector for EDX mapping. Talos F200C is a multi-purpose microscope for life-science and chemistry applications.
