Desert Valley Testing

Desert Valley Testing (DVT) is a credible laboratory that employs industry educated and experienced Chemists to ensure the most accurate analytical testing of your cannabis product. Our laboratory was developed using the laws and regulations governed by the Environmental Protection Agency (EPA) for good laboratory compliance.

We believe it is important to help ensure the health and safety of consumers and to maximize the quality of our client’s products. To that affect, DVT uses science based methodology and chemistry for proper analysis of cannabis products for cannabinoid potency, terpenes, residual solvents, and screening for visible mold. We have the ability to partner with other local laboratories to analyze for heavy metals, pesticides, growth regulators, gender testing, DNA profiling and spore count analysis. Our laboratory utilizes a Agilent 6890/5973 GCMS’s coupled with liquid and headspace autosamplers for residual solvents and terpenes. We use Agilent 1100 HPLC’s for proper determination of potency on a wide range of cannabis products.
