Vitrotem offers an easy-to-use automated system for the fabrication of Graphene Liquid Cells (GLCs). Fabricated on a standard TEM grid, GLCs allow a researcher to record Transmission Electron Microscopy on liquid samples in a conventional TEM system - without the need for vitrification or the use of special sample holders. GLCs enable dynamic TEM imaging of whole biological cells as well as single molecules and nanoparticles in liquid at unprecedented resolution.
