Talos L120C Transmission Electron Microscope

The Thermo Scientific Talos L120C TEM is a 20-120 kV thermionic (scanning) transmission electron microscope uniquely designed for performance and productivity across a wide range of samples and applications, such as 2D and 3D imaging of cells, cell organelles, asbestos, polymers, and soft materials, both at ambient and cryogenic temperatures. The Talos L120C TEM is designed from the ground up to allow users at any skill level to acquire high-quality results with minimal effort. Fast, sophisticated automation and advanced 3D imaging workflows allow applied researchers to focus on scientific questions rather than microscope operation.

Talos L120C Transmission Electron Microscope advantages

The Talos L120C TEM takes imaging to the next level with the optional, motorized, retractable cryo box and low-dose technique, producing quality images even for beam-sensitive materials. To enhance productivity, especially in multi-user, multi-material environments, the constant-power objective lenses and low-hysteresis design allow for straightforward reproducible mode and high-tension switches.

The large pole-piece gap of the high-contrast C-Twin lens, which provides high application flexibility, combines with a reproducibly performing electron column to give you new opportunities for high-resolution 3D characterization, in situ dynamic observation, and other diffraction applications, with a special emphasis on high-contrast imaging and cryo-TEM.

Transmission electron microscope automation

Designed for multi-user and multi-discipline environments, and equipped with a familiar user interface (UI) shared across all Thermo Scientific TEM platforms, the Talos L120C TEM is ideal for novice and expert users alike. All daily TEM tunings have been automated to provide the best and most reproducible setup, easing the learning curve for novice operators, reducing tensions in a multi-user environment, and improving time-to-data for the experienced user. The Talos L120C TEM also offers educational online help embedded within the UI.

Additionally, Thermo Scientific Maps Software enables intuitive image-based navigation over a whole sample along with easy correlation of results across imaging platforms. In order to retrieve large-area imaging at high resolution, Maps Software automatically acquires and stitches images, documenting the entire area of interest with exceptional quality. It supports image import, overlay, and alignment from other microscopes, such as scanning electron or light microscopes. This allows for digital zoom from correlated low-magnification TEM and/or SEM to high-resolution TEM (HRTEM), providing valuable contextual information.
