Concentrates testing
Extracts concentrate everything, including what you did not want. Potency and terpenes tell you what the process captured; residual solvents and metals tell you what it carried through from the equipment and the starting material.

Sample requirements and shipping
| Item | Requirement |
|---|---|
| Shatter, wax or rosin | Requirement1 g in the retail container |
| Distillate or oil | Requirement1 g sealed |
| Vape cartridge | Requirement1 cart, unopened |
| Condition | RequirementIn the container it ships in. We photograph it on arrival and the photograph goes with the certificate. |
Order first, then ship. A prepaid label is emailed when payment lands, and the carrier scan on that label opens your chain of custody. We accept no walk-in drop-off, and we hold no DEA registration, so no Schedule I to V material.
Why the method matters
Extraction concentrates pesticides along with cannabinoids, often by a factor of three to five. A residue that passed on flower can fail on the extract made from it, which is why screening the concentrate rather than relying on the input result is the safer programme.
Residual solvent limits are set by class: class 1 solvents like benzene have limits near the detection floor, class 2 are higher. We report each analyte with its own limit so a pass is not a single word covering sixteen very different numbers.
What comes back
A public certificate
Every result, the method, the instrument ID, the LOD and LOQ and the signature, verifiable by accession number with no login.
The filmed route
Your package opened on camera, a photograph of each container, and the footage retained for three years. Released to you on request.
A retained sample
Held 90 days, so any result can be rechecked by us or by an accredited laboratory of your choosing.
Questions about concentrates testing
Do I need residual solvents on rosin?
Solventless material has no process solvent to find, but we still see hydrocarbon carryover from shared equipment. Most buyers require the test regardless, and it is inexpensive.
Why did my extract fail pesticides when the flower passed?
Concentration. A residue near the limit on flower typically lands three to five times higher in the extract. The input result does not transfer.
Do you screen for vitamin E acetate?
Yes, by LC-MS/MS, and it is included in the vape-focused panel. It is a cutting agent nobody should find, and it is cheap to rule out.
Can you report per-cartridge rather than per gram?
Yes. Tell us the fill weight at submission and the certificate carries mg per cartridge alongside mg/g.
