Talos Arctica

200 kV FEG electron microscope

Designed for rapid, stable, high-resolution data collection of frozen-hydrated samples.

The Talos Arctica is equipped with:

Autoloader system that permits loading of up to 12 specimens.
Automated data collection at liquid nitrogen temperature.
Constant-Power^TM objective lens for optimal contrast/resolution balance.
Volta phase plate, which significantly enhances low-resolution contrast.

Electron cryo-microscopy (cryo-EM) single particle and electron cryo-tomography (cryo-ET) data can be collected automatically with the Thermo Fisher Scientific Falcon lll detector using EPU and TOMO software packages.

Electron diffraction data can be collected with the Thermo Fisher Scientific CETA-D detector in a continuous mode using EPU-D software package.
