Graphene film coated ultra-flat thermal SiO2 grids

These grids are created by coating our existing grids with graphene. Through a unique drop method, a graphene solution is dispersed onto the carbon grid with specific layers.  CharacteristicsFour thicknesses of CVD grapheneAvailable in either 1, 2, 3-5 or 6-8 layersTEM SubstrateThe Ultra-flat Thermal SiO2 Substrate consists of a 200nm thermally grown SiO2 film on an ultra-flat silicon wafer with a normal thickness of 675um. The size is 5 x 5mm.Graphene coverage of the TEM grid is better than 75%
