EPU

Exclusively designed for use within FEI's Cryo-TEM workflow to handle demanding structural biology applications that require high and intermediate resolutions.  EPU brings powerful automation and reliability that delivers impressive results when conducting single particle analysis to resolve 3D protein complexes with the FEI's Titan Krios and Tecnai Arctica TEM microscope platforms.

EPU software operates your instrument and collects data, removing the need for full-time operator control and presence. This software automatically focuses the instrument and ensures the most stable conditions before collecting superior images . Unique algorithms allow EPU  to select thin specimen patches autonomously, using preset experimental variables like drift limits.

This solution will allow you to significantly increase your sample throughput, data collection and time-to-data. 

EPU Benefits

  • Automated, high speed solution for single particle acquisition
  • Fastest available software for single particle analysis
  • Reduced time to data collection
  • Optimized for stable, high throughput particle collection
  • Tailor made recording schemes for commonly used grid types
  • Intuitive, graphic display of experimental set-up that’s easy to use
  • Designed for Tecnai and Titan Krios TEM platforms
  • Connects with the best available detection modules
