Equipment

Stillwater Labs uses Shimadzu analytical instruments that are maintained through Shimadzu’s Montana field office. The Shimadzu line of test equipment is at the forefront of cannabis testing and has been used and validated in all other medical marijuana states in the US. Shimadzu’s instruments are a great balance of high-end function, ease of use, robustness, and cost of operation that allow Stillwater Labs to offer competitively priced analyses, on time.
Stillwater Labs has a newly commissioned LC-2030C high performance liquid chromatograph for potency testing, a GCMS-QP2020 gas chromatograph with a quadrupole mass spectrometer and HS20 headspace autosampler for terpene, solvent, and pesticide analysis, and MOC63U moisture balances to measure water content.
Our equipment is installed in a dedicated access-hardened climate-controlled room to ensure consistency and security of your product and analytical data.
As a requirement for ISO accreditation, Stillwater Labs references ISO 17025 accredited labs for cross-checking our analyses and for peer-to-peer consulting.
