ProSpore® Ampoule is a self-contained biological indicator available for use in steam sterilization, and appropriate for use in healthcare applications.

It is intended for use as a challenge to steam sterilization at 121°C. ProSpore® Ampoule is ideal for use in validating the sterilization of volumes of liquid that takes a longer time to reach sterilizing conditions. No activation is required: just expose the unit in a sterilizer and incubate afterward.

ProSpore® Ampoule is a hermetically sealed, type I borosilicate glass ampoule. The ampoule is filled with a modified Soybean Casein Digest Broth containing bromocresol purple acid indicator. Each ampoule also contains a population of G. stearothermophilus spores*. Growth is evident by either turbidity and/or a color change from a purple to or toward yellow. ProSpore® Ampoule is a refrigerated item requiring expedited shipping.
