Titan Krios G3i S/TEM microscope from Thermo Fisher Scientific (TFS) is used for advanced, high-throughput, high-resolution 3D imaging and structural elucidation of proteins, cells and other biological specimens by cryo-TEM single particle analysis, and cryo-(S)TEM tomography. It features an AutoLoader that holds up to 12 cryo-preserved specimens, two direct electron detectors (TFS Falcon III and Gatan K3), energy filtering and software for automated imaging. There are three annular dark field and one bright field STEM detector. One of the DF detectors features four quadrants for phase STEM imaging (iDPC method).
