The Titan Krios microscopes are dedicated to high-end data collection. However, specimen preparation optimization and checking is necessary in order to assure the best quality samples for data collection.
Therefore at NeCEN a screening electron microscope is available (120 kV). The screening microscope is meant to be used to check and/or optimize specimen preparation conditions (sample concentration, ice thickness, grid quality) as the subsequent step after sample vitrification using a cryogenic plunger. The screening microscope can also be used for teaching purposes and/or demonstrations.
