How to Submit a Hemp Sample for Potency Testing with Ionization Labs

At Ionization Labs, we want to help ensure that your samples arrive at our lab without experiencing any issues during the process. Our goal is to make third-party and in-house potency testing as accessible and standardized as possible. If you are curious about submitting a hemp potency sample to Ionization Labs, please utilize the following steps:

1. Order a Sample Through our Online Store

In a web browser, visit our product page and select either the Premium 24 Hour Potency Test or our Standard 72 Hour Potency Test.

  • Ionization Labs offers multiple bulk testing packages that can reduce the cost of testing. Determine the quantity of test(s) needed and the time-frame the results need to be reported.

Add the applicable items to your digital cart.

  • If bulk samples (5 pack, 10 pack) are submitted separately at a later date, the submitter will need to complete a separate Sample Intake Form/Chain of Custody for each respective shipment.
  • Bulk orders can be maintained as a store credit and do not need to be submitted together. When submitting the sample intake form for additional samples, ensure to use the original order # received.

Once the test(s) have been added to the cart, select "Check Out” 

After you have logged in or created an account with us, review the items in the cart. Proceed by entering address and billing information.

You should receive a confirmation once your order was successfully placed and confirmed.

3. Prepare Your Samples for Submission

How much sample is required for testing?

  • 3 to 5 grams dry/wet for plant material (biomass, flower, bud) - per sample analysis
  • 0.5 to 1 gram for oil, wax, shatter, distillate & isolate, concentrates/extracts, vape oils - per sample analysis
  • 3 grams of topical (roll-ons, lotions, creams, gels, salves) – per sample analysis
  • 3 to 5 pieces of edibles and capsules – per sample analysis
  • 5 mL tinctures and infused oils - per sample analysis
  • 5 mL for beverages - per sample analysis

Please ensure that bud/flower sample(s) are within 5 - 12% dry weight (moisture content) per USDA Laboratory Testing Guidelines. If your sample is not dry or cured, our laboratory will dry your sample on your behalf. This will delay your analysis and your sample results could be subject to a 24 to 72 hour delay. CTS is not responsible for delays due to the client's failure to provide test-ready material.

Sample intake ends at 2 PM CST. If a sample is received and processed after that deadline, it will be tested the following day. Ionization Labs is open Monday to Friday from 8:30 AM to 5 PM. No samples will be processed during the weekends. If you have any further questions, please call us at (737) 231-0772.

Samples should be clearly labeled with:

  • ILCTS identification number provided after sample intake form is submitted
  • Company and/or Client Name
  • Sample Name
  • Batch ID(optional)
  • Date Sample taken (if applicable)
