R&D Test Analysis

  • Moisture Content
  • Mold
  • Mycotoxins
  • Pesticides (not available for flower)
  • Potency
  • Residual Solvents
  • Terpenes
  • Vitamin E Acetate
  • Water Activity

Step 1 R&D Test Process and Checklist

Have the following information ready, we’ll need this for your appointment:

  • Name
  • Business name, if applicable
  • Address
  • Phone number
  • License number, if applicable
