Electron Microscopy Sciences Graphene Oxide 1 Layer on Thermal SiO2 on Ultra-Flat Silicon
Graphene oxide on ultra-flat thermal SiO2.
Type: 1 layer
Electron Microscopy Sciences Graphene on Thermal SiO2 on Ultra-Flat Silicon, 3-5 layers, 1.0-1.7 nm thick, 85.8-90.4% Transparency
CVD graphene on ultra-flat thermal SiO2. The high quality graphene is produced by chemical vapor deposition, a process by which gaseous reactants are deposited onto a substrate. The Ultra-flat Thermal SiO2 Substrate consists of a 200 nm thermally grown SiO2 film on an ultra-flat silicon wafer with a normal thickness of 675 um. The size is 5 mm x 5 mm. Graphene coverage of the TEM grid is better than 75 percent. Available in four thicknesses of CVD graphene, 1, 2, 3-5, and 6-8.
Layers: 3-5 layers
Thickness: 1.0-1.7 nm
Transparency: 85.8-90.4%

These ultra-flat wafers can be used for substrate studies or as substrate for AFM and SEM samples by cleaving the wafer.
Diameter: 150 mm
Orientation: <100>
Thickness: 675 µm±20 µm
Roughness: Typically 2-3Å
Resistivity: 10-20 Ohm-cm
Electron Microscopy Sciences Graphene on Lacey Carbon on 300 Mesh Cu Grid, 6-8 layers, 2.1-2.8 nm thick, 78.5-83.2% Transparency
CVD Graphene TEM support films supported by lacey carbon film on a 300 mesh copper TEM grid. The high quality graphene is produced by chemical vapor deposition, a process by which gaseous reactants are deposited onto a substrate. The graphene film appears as a near-transparent to light-grey film on the surface of the lacey carbon mesh on a red-brown colored copper TEM grid. Graphene coverage of the TEM grid is better than 75 percent.
Layers: 6-8 layers
Thickness: 2.1-2.8 nm
Transparency: 78.5-83.2%
Electron Microscopy Sciences Formvar/Carbon Film 15-20 nm/1 nm thick on Thin Bar Square 400 mesh Copper Grid
A formvar coated grid, stabilized with evaporated carbon film. This type of coating is excellent for specimen support, especially for ultra thin sections. Coated grids are optically checked followed by batch testing in the electron microscope. Packed in grid storage box. NOTE: All film is laid on the shiny side of the grid. Formvar is 15 to 20 nm thick with a 1 nm carbon coating.
Grid: Copper
Electron Microscopy Sciences Quantifoil Holey Carbon Film R 2/2 on Copper 200 mesh Grid
QUANTIFOIL is a perforated support foil with pre-defined hole size, shape and arrangement. It has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) microscopy when compared with conventional holey film.
QUANTIFOIL with circular holes is used in cryo-electron tomographic reconstruction. The roundness of the holes is advantageous with respect to the formation of an ice layer of constant thickness. The whole size chosen depends on the magnification used, and on whether or not one wishes to include support film in the image. Assessment of the image quality is easier when foil is included in the picture, because the power spectrum of a foil is stronger than that of unsupported ice.

Electron Microscopy Sciences Graphene on 2000 Mesh Cu Grid, 6-8 layers, 2.1-2.8 nm thick, 78.5-83.2% Transparency
CVD graphene on microporous copper TEM grids with beryllium-copper support aperture. The graphene film appears as a near-transparent to light-grey film on the surface of the red-brown microporous copper TEM grid. For support, the TEM grid is attached using epoxy to a gold-colored beryllium-copper disk with a 2 x 1 mm aperture. Graphene coverage of the TEM grid is better than 75 percent.
Layers: 6-8 layers
Thickness: 2.1-2.8 nm
Transparency: 78.5-83.2%
