Sonoma Lab Works

Based just below the Emerald Triangle, Sonoma Lab Works is an ISO-accredited, BCC-licensed testing lab that offers state-of-the-art services to clients throughout California.  

We believe that our origin as an in-house lab to one of Northern California’s largest cannabis manufacturers gives us a special insight to both our clients’ needs for timely and consistent turn around times, and the importance of R&D testing in product formulation.  

We work with you every step of the way, using transparent science to ensure accurate and timely results. Thinking of making a switch in labs? We want to offer new clients 10% off your first compliance or R&D order.   Contact us: (707) 757-7748 or
