C-flat™ Holey Carbon Films

C-flat™ is an ultra-flat, holey carbon film with a thickness of about 20 nm supported by a standard transmission electron microscopy (TEM) grid. The ultra-flat surface results in better particle dispersion and more uniform ice thickness. Manufactured without plastics, C-flat™ grids are clean upon arrival and the user has no residue to contend with. Patterning is done using deep-UV projection lithography, ensuring the most accurate and consistent hole shapes and sizes down to submicron features. The precise patent pending technology by which C-flat™ is manufactured elminates artifacts such as excess carbon and edges around holes. C-flat™ products are fully specified by 4 parameters: the hole diameter and hole spacing of the holey carbon film and the material type and mesh size of the TEM grid (pictured).
