Product Detail

CAS No.: 7782-42-5

ACS Graphene TEM Support Films are supported by a lacey carbon film on a 300mesh copper TEM grid.
 
Characteristics
1. Four thicknesses of CVD graphene:
Available in either 1, 2, 3-5 or 6-8 layers
2. TEM Substrate: 
Lacey carbon support film on 300 mesh copper TEM grid (Grid Hole Size: 63µm)
3. Graphene coverage of the TEM grid is better than 75%. (The graphene coverage is typically >75% of the whole 3.05mm diameter TEM grid.)
Appearance

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.
