Available from NAMSA
NAMSA offers spore ampules for use in monitoring the efficacy of steam sterilization processes. Spore ampules are ideal for use in validation of liquid sterilization cycles. No activation is required; simply expose spore ampule to sterilization process and incubate. Spore ampules are available in several configurations.
All spore ampules are hermetically sealed type I borosilicate glass containing a modified Soybean Casein Digest Broth with bromocresol purple pH indicator and the specified population of Geobacillus stearothermophilus spores. Growth is evident by either turbidity and/or a color shift from a purple to or toward a yellow color.
