*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.

Do you need assistance with Raman measurements on your custom/modified graphene sample? We can help! Please inquire at support@grolltex.com or call (858) 368-9065 for details.

 

Tips Safety Data Sheet

 

  • 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.
  • 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.
  • We have taken the guesswork out of your project by analyzing every piece of graphene that leaves the door. Take advantage of the data files available for your graphene batch. Contact us if you require additional characterization of your graphene.
  • If you have modified a piece of graphene you have received from GrollTex and need Raman measurements taken of your sample, we can assist you. Please contact us at support@grolltex.com or (858) 368-9065 for more information.
