Our dialed-in science team excels at testing everything from potency to terpenes.

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. Focus on cannabis science. Don't be tempted by "industry-friendly" labs who provide false results to quickly move product to retail. These labs don't provide useful analytics or quality control. Shortcuts lead to safety concerns and loss of consumer confidence. Not to mention increased regulatory scrutiny. Choose a lab that is ISO 17025 accredited and legally defensible.

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.

Moisture & Water Activity - $25

Our methods for testing moisture content in cannabis use 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.

Microbial Testing (Enumeration) - $50

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.

Mycotoxin Testing - $50

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 Analysis (11-compounds) - $50

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.

Terpene Analysis - $50

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.

Residual Solvent Testing - $50

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 be used on different matrices including pharmaceuticals.

Full I-502 Cannabis Testing - $75

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.

Research and Development (R&D) - $125

Ask about our R&D packages. Our cannabinoid research package provides quatitation of 11 cannabinoids, and also included are chromatograms, data comparison. full wavelength UV-Vis spectra and interpretation of results by our PhD Scientific Director.

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.

Double Combo - $75

Bundle any two of the following tests: cannabis potency, microbial, residual solvent or terpene. 

Triple Combo - $100

Bundle three of the following tests: cannabis potency testing, microbial, residual solvent, or terpene.
