Substrate
Our 25 micron-thick copper foil is sourced from a reliable, quality-assured supplier in the United States. As part of our commitment to delivering the highest quality graphene at affordable prices, our in house substrate processing results in copper grain sizes that are tens square centimeters in area.
3” x 3” graphene/copper foil pieces are secured to their underlying plastic containers with four small PDMS droplets, one in each corner. Gently peel the foil from the PDMS droplets to release it from the plastic container.

Tips
To ensure the maximum shelf life of your graphene sample, it is best stored under vacuum or in inert atmosphere (Argon or Nitrogen) conditions once the vacuum sealed package has been opened.
3” x 3” graphene/copper foil pieces are secured to their underlying plastic containers with four small PDMS droplets, one in each corner. Gently peel the foil from the PDMS droplets to release it from the plastic container. Please recycle your containers when they are no longer needed!
Please keep the product serial number you receive with your sample, as it will assist us if you have inquiries about the product. The serial number (S/N) is located on the clear vacuum-sealed bag your graphene sample arrived in and your invoice.
