Frequently Asked Questions

What does Reagent Grade mean?

Reagent Grade is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Reagent Grade is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
