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%
Electron Microscopy Sciences TEM Window Grid Silicon Nitride Film, 1000 µm, 50 nm
Silicon Nitride TEM Window Grids perform well under harsh conditions. They tolerate temperatures above 1000 deg C and support use in environmental TEMs where dynamic processes are observed at high temperatures. They provide an ideal balance of imaging resolution, chemical stability and mechanical strength. They can be vigorously plasma cleaned to remove organic contamination. The incorporate LPCVD, low-stress(~250MPa), non-stoichiometric silicon nitride to provide flat, insulating and hydrophobic surfaces.
Silicon frames are 100um thick. There is less than 0.5 nm variation in film thickness across an entire production log, not just a single window grid. Grids fit standard 3mm holders and most double tilt holders. They come in clear gel-boxes for simpler sample preparation. Use: demanding conditions.
Dimensions: 1000 µm
Thickness: 50 nm

Electron Microscopy Sciences Graphene on Lacey Carbon on 300 Mesh Cu Grid, 2 layers, 0.7 nm thick, 92.7% 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: 2 layers
Thickness: 0.7 nm
Transparency: 92.7%
Electron Microscopy Sciences Gilder Finder Grid F1, 400 mesh Nickel Grid
Used to identify specific areas of mesh by an alphabetical or numerical code built into the mesh. 3.05 mm diameter, 0.7 mil (18 um) thickness. The block of 1152 (32x36) individual cells is divided into smaller blocks bounded by thicker crenellated bars. Each small block of 36 (6x6) cells has a central number from 1 to 32 for identification.
Grid: Nickel
Electron Microscopy Sciences Quantifoil Holey Carbon Film R 10/10 on Gold 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 Quantifoil Holey SiO2 Film R 2/2, Copper 400 mesh Grid
QUANTIFOIL is a perforated Silicon dioxide SiO2 support foil with pre-defined hole size, shape and arrangement. Used in cryo-electron microscopy at magnifications between 30,000x and 40,000x. 2 µm hole and 4 µm period.
Electron Microscopy Sciences EMS Lacey Carbon Film 4-6 nm thick on 400 mesh Gold Grid
This carbon coated film on a broken pattern consists of woven-mesh-like holes of different sizes and shapes. This type of pattern provides support but does not interfere when observing specimen sections. All of our coated grids are optically checked followed by batch testing in the EM. Packed in grid storage box. NOTE: All of our film is laid on the shiny side of the grid.
Grid: Gold
Thickness: 4-6 nm
Electron Microscopy Sciences Lacey Carbon Film with Carbon/Formvar 1 nm / 5 nm thick on 400 mesh Gold Grid
The continuous ultrathin carbon/formvar film on lacey carbon allows for the thinnest support film that still has adequate strength to withstand electron microscope specimen preparation. The carbon 1 nm, formvar 5 nm film lies across a carbon lacey film supported by a mesh grid. The size of the holes in the lacey film differ widely from batch to batch but are generally in the range of ¼ µm to 5µm, which gives the equivalent support of at least 6000 mesh grid.
Specimen material lying over the covered holes can be imaged in the TEM with practically no interference from the carbon film supporting it. This product is ideal for looking at nanotubes, virus particles and other small particulate material.
Grid: Gold
Electron Microscopy Sciences Holey Carbon Film with Ultrathin Formvar 3-4 nm thick on 200 mesh Copper Grid
