Grolltex Products and Graphene Sheets for Sale Terms and conditions

All of our products at Grolltex are fabricated and packaged in a Class 1000 cleanroom. Adhering to our strict procedures and processes allows us to achieve high-yield, high-quality CVD graphene production, resulting in exceptional graphene quality at an affordable price. Every batch of graphene is analyzed meticulously and comes with a datasheet unique to your specific batch of graphene, so that the customer always knows the metrics that are most important to them. The individual specification sheet provided for each unit of graphene sold by Grolltex contains optical images of graphene from the batch transferred onto Si/SiO2, FET mobility on Si/SiO2, sheet resistance, and Raman spectra. We are happy to provide the batch-specific sampling spectra txt/scv files to our customers upon request. Each graphene sheet is vacuum sealed in a clean and inert nitrogen environment. Secondary packaging of our graphene under positive nitrogen atmosphere in a moisture-proof, light-proof, static-proof cleanroom bag ensures prolonged shelf-life when not in use by the customer.
