Graphene TEM Grid
Innovative TEM grid with high-purity CVD-synthesized bilayer graphene free-standing film over grid holes.
Ideal sample support film for TEM observations of ultrafine particles, viruses, etc.
Very thin vitreous ice layer with uniform thickness, which is indispensable to cryo TEM observations,
can be formed by applying hydrophilic treatment to bilayer graphene.
We can also provide a hydrophilized graphene TEM grid.
It is a TEM grid that uses jighly clean CVD bilayer graphene and has outstanding electron beam irradiation resistance.Also strong against hydrophilic tretment using such as UV and plasma irradiations.
