Residual Solvent Testing

Residual Solvent Testing

Concentrates

When manufacturing cannabis concentrates, chemical solvents are often used to extract the active compounds from the resin glands of the plant matter. While effective in producing highly concentrated extracts, the residual solvents are often times not purged completely and can be hazardous to health if inhaled or consumed. 

Anresco Laboratories can test for many solvents, including all 20 of the residual solvents required by the State of California for Phase I and Phase II of compliance testing. Contact us if you’d like to test for a solvent not on this list!
