The glassine packaging provides protection from environmental contaminants during transport post exposure. The spore strips can be easily removed from the glassine pouch by tearing the pouch open for transfer to culture media or challenge device assembly. Spore strips are available in populations from 102 to 108 for each organism. A lead time may apply for population levels not outlined in the tables below.

Our most popular spore strips are manufactured using state of the art equipment, which provides assurance that each glassine envelope contains a BI consistent in population, purity and dimension. Spore strips are packaged in shelf packs of 100 and labelled with a 24 month shelf-life based on the organism. Store strips at room temperature conditions (15 - 30˚ C). Each pack is accompanied by a certificate of analysis. Spore strips are certified for population, purity, and resistance (D value, z value, survival and kill where applicable). Excelsior Biological Indicator strips are compliant with ANSI/AAMI/ISO/ EN 11138 series of standards and USP where applicable.
