Tryptic Soy Broth is recommended for use as a general purpose medium for the isolation and cultivation of a wide variety of bacteria and fungi. The U.S. Pharmacopeia National Formulary (USP) describes its use for sterility testing.

Hardy Diagnostics' sterility media and rinse solutions are manufactured in an ISO 13485 environmentally controlled production center. Each lot is certified for pH, sterility and growth promotion using ATCC® strains specified by the USP. Our approach to manufacturing ensures all sterility media and rinse fluids provide the highest level of clarity for improved reading accuracy, thus significantly reducing the risk of incorrect interpretation and false results.
