Calibration Standards

Cannabinol (CBN), DEA Controlled Substance, 1,000 ug/mLin Methanol While the legalization of cannabis for both medicinal and recreational purposes has been gaining speed, legislation and regulation has not necessarily kept pace. Out of a drive for self-regulation and significant consumer safety concerns, many producers and manufacturers are turning to testing labs in order to ensure that their products are of high quality and free of chemical contaminants. SPEX CertiPrep offers ISO/IEC 17025 and ISO 17034 Certified Reference Materials (CRMs) for all of the common contaminants such as pesticide residues, residual solvents and heavy metals, as well as qualitative analysis CRMs, such as terpenes. As the industry demands change and regulations are put into place, we continually update our product offering.

Sodium Oxalate, Powder, Primary Standard, Reagent Special, ACS, also known as disodium oxalate, is used as a primary standard for standardizing potassium permanganate solutions. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
