The 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. The zero-loss filtering of the Selectris Filters removes noise caused by inelastically scattered electrons, producing an increased signal-to-noise ratio (SNR) and better contrast. Designed for high stability, the zero-loss peak position of the Selectris Filters is insensitive to temperature variations in the environment, eliminating the need for frequent tuning.

Paired with the latest generation Thermo Scientific 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-electron microscopy (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.

The Selectris and Selectris X Imaging Filters are available on Thermo Scientific Krios and Glacios Cryo-TEMs.
