Biological Indicators


NAMSA offers the industry's most complete line of Biological Indicators (BI) designed to meet the ANSI/AAMI/ISO/EN 11138 standards.

NAMSA Biological Indicators are:

    • Used to evaluate the effectiveness of sterilization processes.
    • Essential in performing sterilization cycle validation.
    • Used for Ethylene Oxide, Dry Heat, Steam and Radiation sterilization processes.
    • Available in a wide range of organisms, populations and packaging.
    • Available as strips (standard size or mini), discs, suspensions, self-contained, ampoules and custom configurations.

Only minimal training is required to use NAMSA Biological Indicators. Following sterilization, spore strips or discs are cultured in Soybean-Casein Digest Broth (SCDB) following U.S. Pharmacopoeia (USP) standards. Alternatively, processed or exposed biological indicators may be returned to NAMSA for testing. Our self-contained biological indicators (SCBI) and spore ampoules may be immediately activated by the user and then incubated for quick results.
