Krios G4 Cryo-TEM
Atomic resolution cryo-EM with enhanced productivity and compact design
he award-winning Thermo Scientific Krios G4 Cryo-Transmission Electron Microscope (Cryo-TEM) enables you to unravel life at the atomic level—easier, faster, and more reliably than ever before. The most compact TEM in its class, the Krios G4 Cryo-TEM consists of a highlTy stable 300 kV TEM platform and the industry-leading Autoloader (a cryogenic sample manipulation robot), making it ideally suited for automated applications such as cryo-electron tomography (cryo-ET), single-particle analysis (SPA), and micro-electron diffraction (MicroED).
Features
Truly atomic resolution performance
The optional Selectris X Imaging Filter with Falcon 4i Direct Electron Detector and E-CFEG cold field emission source improve image contrast to reach higher resolutions in shorter time.
Maximized productivity through automation
Advanced Performance Monitoring ensures the best optical starting point for automated runs and Thermo Scientific Smart EPU Software enables automated grid screening, quality monitoring, and data management.
Workflow connectivity
Designed for easy exchange of cassettes, facilitating a smooth transfer of specimens between Autoloader-equipped TEM instruments, and equipped with Thermo Scientific Athena Software to manage experimental parameters and data.
Easier to fit into new or existing labs
Redesigned internal base frame and system enclosure reduce height below 3 m (10 ft) while enhancing system performance and preventing costly room renovations.
