biochemicalgrade
Biochemical grade is a designation used in laboratory supply to describe materials intended for use in biochemical and life-science experiments. It indicates a level of purity and material compatibility designed to minimize interference with biological systems, while not necessarily meeting the stricter regulatory requirements imposed on pharmaceuticals. Materials marketed as biochemical grade include reagents such as buffers and solvents, enzymes and substrates, nucleic acid preparations, cell-culture additives, and water intended for biological use (biochemical-grade water).
Purity criteria vary by supplier but commonly include limits on trace metal content, particulates, residual solvents,
Biochemical grade is distinct from other common lab grades. Analytical grade or ACSGrade materials are intended
In practice, researchers select biochemical-grade reagents and water based on intended application, verifying COAs, storage conditions,
