When it comes to the success of your medically endorsed products, nothing could be more important than using a reputable cannabis lab. Testing ensures your protection from a compliance perspective, but it’s also critical to the health of immune-compromised people who use cannabis as medicine.
Our industry-leading science team, state-of-the-art equipment, and ISO 17025 accreditation ensure your products are tested at the highest standard. Seattle’s medical marijuana community deserves a testing lab that makes accurate testing their mission.
Our method for testing moisture content in cannabis uses both a loss on drying technique to determine percent moisture, and measurement of water activity. Water activity is measured using an Aqualab DUO 4TE, the industry standard for dew point moisture analysis. USP <1112> outlines water activities required to support microbial growth.
Our in-house pesticide chemist, Kyle Shelton, helps us perform medical marijuana tests with industry-leading expertise.
Pesticides are commonly used to protect crops from diseases and pests. However, no pesticides have been validated for use on cannabis flower, which leads to people misusing and overusing these harmful products. In order to achieve accurate quantitation of pesticide residues, we use a Shimadzu 8050 LCMS Triplequad to detect 140+ pesticides.
COMING SOON: We perform metals analysis using a Shimadzu ICP-MS 2030 (Inductively Coupled Plasma Mass Spectrometer). Digestions are accomplished on an Anton Paar Multiwave GO. Our metals list covers the WA State DOH required heavy metals arsenic, cadmium, lead, and mercury in addition to a broad panel of inorganics. Methods include USP <232> and <233>, EPA 200.8, and a modified EPA 6020.
From state-of-the-art technology, to a team made up of cannabis scientists, we not only provide the best testing — our experience in the cannabis industry can help you improve your business.
Optimize your grow operation and processing, keep customers coming back because of your reliable products with the knowledge you gain from our lab team. Choose a lab that is ISO 17025 accredited in addition to WA state certified.
Our commitment: To provide the best analytics and quality control for testing of cannabis, including industry-leading research and support. Recreational consumers and medical marijuana patients deserve to purchase cannabis products that are clean and safe for consumption. We take quality assurance and product safety seriously.

Our dialed-in science team excels at testing everything from potency to terpenes.
We test cannabis products for aerobic, yeast and mold, gram-negative bacteria, coliforms, E.Coli, and salmonella. Our industry-standard, validated methods utilize 3M™ Petrifilm™ to ensure we accurately detect these microorganisms and pathogens. We also work with Romer Labs, a leader in the food safety industry, who created specialized assays and validated them for the cannabis industry.
Mycotoxins are known carcinogenic compounds produced by molds. We use an enzyme-linked imunnoassay (ELISA) and LC/MSMS to detect and verify the presence of Aflatoxin B1, B2, G1, G2, and Ochratoxin A in cannabis flower.
Cannabinoids are quantified on a Shimadzu Nexera UFLC 2040 with PDA (photodiode array detector). Our cannabinoid method quantifies CBGA, CBG, CBD, CBDA, CBDV, CBN, CBC, Δ9-THC, THCA, Δ8-THC, and THCV in various cannabis based products including flower, extracts, concentrates, tinctures, topical products and edibles.
We separate cannabinoids using liquid chromatography and measure them by UV detection with photodiode array.
Terpenes are the aromatic and flavor compounds found at varying concentrations among the different strains of flowers on the market. They occur in unique ratios and may play a role in how cannabinoids interact with the body. We offer terpene analysis for cannabis flower, extracts and concentrates. We quantify 30+ terpene and terpenoid compounds using gas chromatography.
We use a GC-FID coupled to a Headspace Autosampler in order to detect and quantify hydrocarbons, and Class 1, Class 2, and Class 3 residual solvents. Our method follows the United States Pharmacopeia (USP) method 467 and can detect and quantify all WA state mandated solvents.
Full I-502 cannabis testing includes cannabis potency testing, microbial screening, analysis for moisture, water activity, mycotoxins, and testing for residual solvents. All 502 testing regardless of sample type (flower, extracts, edibles) are offered at the same low price.
Note: edibles do not require microbial or solvent tests, although their complex nature requires more work for sample preparation in order to accurately report. Therefore, edibles pricing is the same as for flower and extracts.

This additional information can be of use when processing concentrates, extracts and distillates. It is also useful for landrace strain identification. Finally, it is valuable information for consumers that can be included on product labels.
Bundle any two of the following tests: cannabis potency, microbial, residual solvent or terpene.
