“*The indicated product metrics are generic to our process. Each graphene unit sold is accompanied by a specification sheet unique to the S/N and contains batch-specific metrics. This eliminates guesswork and ensures that you only get the best, well-characterized, and QA-passed graphene.
Data files for mobility and Raman measurements are available upon request. Please send an email including your name, institution, and product serial number to support@Grolltex.com and indicate which file(s) you would like.
