3-5Graphene electron microscope grid (copper grid)

Overview
This product features 3-5 layer graphene grown via chemical vapor deposition (CVD) and transferred onto 2000-mesh copper TEM grids. The CVD process utilizes transition metal substrates—particularly copper—which promote surface-catalyzed growth for controlled layer formation. The graphene is specifically prepared for electron microscopy applications, providing researchers with a ready-to-use sample for structural and property characterization at the nanoscale.
