What are your sample size requirements?

It is necessary that your sample size meets our minimum sample size requirements, which varies based on the type of test requested and the sample matrix being submitted.


  • Plant material (flower, biomass, etc.): 2 grams
  • Concentrates: 1 gram
  • Infused Products:
    • Edibles: 4 units/pieces
    • Tinctures: 1 mL
    • Topicals: 2 grams
  • Waters/Drinks: 60 mL or 1 resealable unit or 3 single use units (i.e. can)

Terpene Profile Analysis:

  • 2 grams / 2 mL
  • Please note: we can’t test capsules or edibles. Submit the oil concentrate.

Residual Solvent Analysis:

  • 1 gram / 1 mL

Microbial Contamination:

  • 1 unit or no less than 3 grams for all sample types. Microbial test samples must be in a separate sample container from samples submitted for all other testing.

Pesticide Screening

  • Plant material: 2 grams
  • Concentrates: 2 grams
  • Liquids: 2 mL
  • Topicals: 2 grams
  •  Please note, we do not provide pesticide testing on finished food/edible products. It is recommended that you control your upstream processes (i.e. verifying plant material and extracts are free from contaminants), thereby mitigating the necessity to test finished products for contaminants.

Heavy Metals

  • Plant material (flower, biomass, etc.): 4 grams
  • Concentrates: 4 grams
  • Infused Products:
    • Tinctures: 4 grams
    • Topicals: 4 grams
    • Food products (e.g. gummies/pet treats, etc.): 10 grams
  • Waters/Drinks: 4 grams
  • If your product is primarily solvent-based, please let us know on the Chain of Custody form.

Water Activity:

  • 1 unit or no less than 2 grams


  • 1 unit or no less than 20 mL


  • 20 mL or 20 grams

Note: Sample sizes are per test. For example, if you require Cannabinoid Potency and Residual Solvent Analysis, you will need to submit 1-2 grams for potency and 1 gram for Residual Solvents.
