Spore Strips


NAMSA offers a full line of spore strips for use in monitoring various sterilization processes including Ethylene Oxide (EO), Dry Heat, Steam and Radiation. Spore strips consist of inoculated filter paper, 6mm x 30mm, packaged in glassine pouches. Spore strips are available in populations from 102 to 108 for each organism.

NAMSA strips are manufactured in shelf packs of 100 with an 18 or 24 month shelf-life based on the organism and date of manufacturer when stored under room temperature conditions. Spore strips are certified for species, population, purity, resistance, (dvalue, zvalue, survival/kill, where applicable) and expiration date.
