  • COMPANY NAME
  • SAMPLE NAME
  • BATCH ID (optional)
  • TEST TYPE
  • TURN AROUND TIME

Enter your account information

Please provide your company information, the accounts payable contact, the primary lab contact, and any additional employees that require access to your client portal.

Sample information section

Sample name

Sample Name
Enter the name of the sample as you would like it to read on your certificate of analysis. Please note, we cannot change the sample name after the analysis has completed. If a different sample name is required, a new sample will need to be submitted.

Batch ID
If you have an internal batch record that you use for tracking, enter that number/lot here. This field is optional. Please note, we cannot change the Batch ID after the analysis has completed. If a different Batch ID is required, a new sample will need to be submitted.

Product Profile Testing Section

Enter all the product profile tests the sample requires on the same row.

Cannabinoid Potency
Our potency test requires additional information so we can accurately test your sample.

Turn Times
Standard = 4 days, Next Day, and Same Day. We have a 10:30am cut-off. Samples received after 10:30am by our Intake department we will be processed the following day.

Report Format
We can report potency in three reporting formats: percentage (%), mg per unit, or mg per ml. Choose one from the dropdown menu.

Percentage is our default format for plant material or extracts. No other information is required for this format. We will report the results in a % and milligram per gram amount.

Report Format Percentage

Milligram per unit is the recommended report format for finished products. The report will calculate the total amount of cannabinoids per container or unit, e.g. one tincture bottle, one capsule, one gummy, etc. This format requires the fill weight in grams of the contents inside the container. Enter the weight of the product in grams in the additional info field.

Report format - mg/unit

Milligram per millilter is used for liquids. In order to calculate potency results in mg/ml, we need to know the density of the carrier oil.

Report format - milligram per mililiter

If you don’t know the density, you will need to select our Density test in addition the Potency test.

Report format - density

Additional Info
If you select mg/unit as the reporting format, enter the fill weight in grams. If you select mg/ml, enter the density.

Concentration
The concentration of the cannabinoids to total weight of your sample will determine how we prepare it for testing. Please select a concentration range from the dropdown menu.

For example, your bottle of tincture has 1000mg of CBD and total weight of the contents is 28.5 grams. The concentration would be 3.57. Select 2 – 5% from the dropdown menu. If you don’t know, select “unknown”.

Step 3: Mail your samples

Once you have prepared your samples and completed the chain of custody form, it is now ready for shipment. Please follow the steps below to ensure that your samples arrive safely at our laboratory.

Include sample documentation

Consider including any documentation that you may have that will identify your samples as hemp or hemp-derived. This could be any state or international cultivation/manufacturing licenses or previous certificates of analysis. If your package gets selected for inspection, postal inspectors won’t know whether your shipment is a legal product or an illegal one without documentation.

Packaging your samples for shipment

Ensuring sample integrity while in transit will be important to avoid any shipping or testing delays. We recommend packaging your samples in a dual container system.

Primary Container

  • Please submit your samples in reinforced, resealable, labeled containers that are suitable for your product matrix.
  • For glass containers, reinforce screw caps with adhesive tape.
  • Affix a proper label to clearly identify the contents.

Secondary Container

  • To prevent breaking or leaking in transit, please reinforce your primary containers properly, e.g. bubble wrap.
  • Use a watertight/leak-proof container or sealable mylar envelope.
  • Reinforce the container using adhesive tape or heat seal.

Shipping

When your samples are prepped and ready for submission, be sure to package everything in a sturdy shipping box, as opposed to an envelope. Please submit a completed chain of custody form as well as labeled samples in your package.
