  • Frozen hydrated biological samples (CEMOVIS)
  • Room temperature sectioning of water sensitive samples
    • Dry resin sectioning of biological samples for chemical analysis
    • Dry sectioning of industrial samples such as polymers


  • The left manipulator moves a conductive fibre on which the sections are attached by electrostatic force; the growing ribbon is guided.
  • The right manipulator guides the grid very precisely below the section ribbon, the sections are attached to the carbon film with electrostatic force.


  • Leica cryochambers FC6 and FC7 equipped with a Crion ionizer/charger
