Glacios 2 Cryo-TEM overview
The Thermo Scientific Glacios 2 Cryo-Transmission Electron Microscope (cryo-TEM) allows you to easily collect near atomic data from a broad range of biological targets. Compared to the previous generation, the Glacios 2 Cryo-TEM delivers higher throughput and makes cryo-EM more accessible. It features an integrated Thermo Scientific Falcon 4i Direct Electron Detector, Thermo Scientific EPU Software, and a new full enclosure, which combine to enhance image quality, automate data acquisition, and simplify your work. The Glacios 2 Cryo-TEM is ideally suited for single-particle analysis, cryo-electron tomography (cryo-ET), and micro-electron diffraction (MicroED).

Key features of the Glacios 2 Cryo-TEM
The Glacios 2 Cryo-TEM provides near atomic resolution. With improved hardware and a new enclosure that minimizes environmental influences, the Glacios 2 Cryo-TEM now has an information limit of 2.1 Å. Similarly, transmission loss due to ice growth has been reduced to 2% over 24 hours, helping you collect more high-resolution images with less effort. When the Glacios 2 Cryo-TEM is configured with a Thermo Scientific Selectris X Imaging Filter, the speed and resolution can be further improved.
High throughput Cryo-TEM image acquisition
The integrated Falcon 4i Direct Electron Detector provides better image quality than its predecessors in less time. To further enhance productivity and image quality, the Glacios 2 Cryo-TEM offers fringe-free imaging (FFI) that eliminates fringes at the edge of the beam, a more stable stage, and faster automated data acquisition. Together, these improvements allow you to collect more images per foil hole and accelerate single particle analysis per foil hole and accelerate single particle analysis and cryo-ET. Adding the Selectris X Imaging Filter allows you to use a very stable narrow slit width (<10 eV) for an additional boost in contrast for single particle cryo-EM and cryo-ET, improving resolution and obtaining results faster with less data to maximize resolution.
See how the Falcon 4i Direct Electron Detector enhances throughput with 10 times shorter exposure times than previous generations.
Aberration-free image shift (AFIS) is an optical mode for faster data acquisition without comprising image quality. AFIS performs large beam shifts without off-axis coma and astigmatism.
Acquire more images per sample area with FFI, enhancing your daily data throughput. Hear how FFI has been helping the daily research in Dr. Elizabeth Villa’s lab.
Maximized ease of use and efficiency
Smart EPU Software enables faster and easier set up and processing, benefiting both expert and non-expert microscopists. Several critical set-up steps have been automated, such as alignment of the column and repair of system status, when possible. In addition, the software and various optional add-ons can help users get the most out of their microscope time and the best possible results.
- Optional Smart EPU Software with EPU Quality Monitor is an AI-enabled software solution capable of analyzing intermediate results, providing instant feedback and steering data collection on the fly.
- Optional Smart EPU Software with Embedded CryoSPARC Live is a turnkey solution for real-time structural feedback on data quality and comes with full service and application support.
- Optional EPU Multigrid Software allows data collection for up to 12 grids to be completed while away from the microscope, ensuring maximum productivity.
- Open application programming interface (API) enables the development of your own functionality for the Glacios 2 Cryo-TEM.
Sample screening is an essential component of successful cryo-EM workflows, allowing verification of sample quality in terms of both biochemistry and vitrification. The Glacios 2 Cryo-TEM fits seamlessly into single particle analysis and cryo-ET workflows with convenient and contamination-free sample transfer throughout the workflow.

Designed for stability and speed, Thermo Scientific Selectris and Selectris X Imaging Filters are post-column imaging filters that improve the contrast of TEM images, resulting in high-resolution structures up to atomic resolution. Paired with the latest generation Falcon 4i Direct Electron Detector, Selectris Filters enable you to obtain high-resolution structures quickly, revealing new biological insights. To further increase the productivity and ease of use of your cryo-EM research, these filters are fully integrated into Thermo Scientific EPU Software, Thermo Scientific Tomography Software, and instrument operation software.
The Thermo Scientific Falcon 4i Direct Electron Detector, with optical and throughput enhancement modes in combination with a more stable stage, accelerates automated data acquisition. Aberration-free image shift (AFIS) functionality uses image beam shifts, eliminating the need to perform mechanical stage movements. Fringe-free imaging (FFI) ensures the beam is only collecting data on usable parts of the sample, improving the quality of the results. When configured with the Selectris X Imaging Filter, the capability to use a very stable narrow slit width (<10 eV) provides an additional boost in contrast for single particle cryo-EM and cryo-ET, improving resolution and obtaining results faster with less data to maximize your resolution efforts. Paired with the Glacios Cryo TEM the Falcon 4i Direct Electron Detector makes it possible to efficiently solve structures routinely at 3.0 Å resolutions or less.
