Excelsior Spore Suspensions are pure suspensions of viable spores with known resistance characteristics and population levels. The convenience of the Spore Suspensions allows for direct inoculation of products, typically to verify sterility of devices where a traditional BI strip cannot be used. They can also be used for a variety of other microbiological tests including cleaning effectiveness studies, Bioburden percent recovery and Bacteriostasis/Fungistasis (BF) testing.
Excelsior Spore Suspensions are packaged in 10 mL volumes and are sold in pharmaceutical grade glass vials with screw cap and septum which allows for withdrawal of the suspension using either a pipette or a needle and syringe assembly. The Spores are suspended in Water for Injection (WFI) in a variety of population levels standardised per 0.1mL. We are also able to provide spores in WFI with up to 40% ethanol mixture upon request.
Spore Suspensions with population levels below 106 are also available upon request; please contact Excelsior for pricing, lead time and availability. Excelsior Spore Suspensions are ANSI/AAMI/ISO EN 11138-1 and USP (where applicable) compliant. The Suspensions are labelled with a shelf life based on the organism.
Spore Suspensions require storage under refrigerated conditions (2˚ - 8˚C). Each vial of Spore Suspension is accompanied by a Certificate of Analysis detailing the source, assayed population, resistance characteristics on paper carrier and expiration date.
