… for your state is challenging.
Luckily, suppliers like CPI International recognize this challenge and offer certified reference standards to streamline cannabis testing in your lab.
With over 30 years of experience, CPI International is a well-respected supplier of certified reference material, laboratory consumables, small equipment, and test kits to scientific professionals working in spectroscopy, chromatography, mass spectrometry, and microbiology - and of course, cannabis testing.

What are the main applications of cannabis testing and why are reference standards required?
Every state in the U.S. is different and has its own set of regulations. If you’re a producer in California, your cannabis oil needs to get tested against California standards. Not Colorado cannabis testing standards or Oregon cannabis testing standards. Only California-specific standards.
Testing cannabis products against the right standards for each state ensures that you meet that state’s specific threshold requirements and test a product to be both safe and effective. That’s why accuracy in your cannabis testing standards is so important. They’re the benchmark of success for every cannabis product you test.
CPI’s pesticide reference standards for cannabis analysis are produced from premium grade materials and prepared in ISO 9001:2015, 17025, and 17034 accredited laboratories, and include Certificates of Analysis in every shipment.
