The Electron Microscopy facility EM Square at Utrecht University is devoted to the development and application of electron microscopy methodologies for life sciences, geosciences, and material sciences research, covering the entire range of specimen preparation, electron microscopy data collection and analysis, and 3D reconstruction techniques. The infrastructure includes several advanced Transmission Electron Microscopes (TEM) and Scanning Electron Microscopes (SEM), with a full range of imaging modes and analytical tools such as bright-field and dark-field STEM, electron diffraction, 2D EDX chemical mapping,  and (cryo) electron tomography. In addition, dedicated specimen holders are available for performing experiments inside the electron microscope, including cryo-, heating, and liquid cell holders.

For life sciences research, the facility houses equipment for the preparation of biological specimens with preservation of ultrastructures (including cryo-fixation, freeze-substitution, and high-pressure freezing of samples), immunolabeling, serial sectioning, and high-resolution electron tomography to study three dimensional structure of cells, tissues, and protein complexes.
