Package
We have taken special care and use vacuum packaging to minimize damage on the research surface of graphene. Our graphene film sample packaging is unique such that the graphene surface does not come in contact with the inner package surface. As a result, our graphene samples are not damaged nor scratched during the shipping process. In addition, we used PET film on the bottom side for protection.
Storage Instructions
To minimize the effects of oxygen, keep the graphene in its vacuum-sealed packaging during shipment, or store it in a vacuum desiccator after opening.
