Thermo Scientific - Selectris and Selectris X Imaging Filters

With the Selectris Filters, zero-loss energy filtering is straightforward due to the thorough integration of software and hardware along with extensive automation and exceptional stability. Every mechanical and electron-optical element has been designed for stability and data reproducibility, enabling the unattended and reliable acquisition of large datasets with narrow energy slit widths (less than 10 eV). The capability to use these narrow slit widths provides an additional boost in contrast for single particle cryo-electron microscopy (cryo-EM), enhancing signal strength, resolution, and throughput.

Paired with the latest generation Thermo Scientific Falcon 4 Direct Electron Detector, Selectris Filters allow you to obtain high-resolution structures quickly, revealing new biological insights. To further increase the productivity and ease-of-use of your cryo-EM workflows for single particle analysis and cryo-electron tomography, these filters are fully integrated into Thermo Scientific EPU Software, Thermo Scientific Tomography Software, and our instrument operation software.

On the rare occasion that filter tuning is necessary, it can be completed automatically within minutes; this ensures smooth daily operation and efficient data acquisition.

Selectris X Filter – taking the next step toward atomic resolution
Expanding on the stability, ease-of-use, and performance of the Selectris platform, the Selectris X Imaging Filter offers an even more sophisticated electron optical system for further aberration correction. This results in extremely low distortion characteristics in both the image and energy domains, opening the way to true atomic-resolution structures.
