Excelsior Steam Biological Indicators

Excelsior offers spore ampoules for use in monitoring the efficacy of steam sterilization processes. Spore ampoules are ideal for use in validation of liquid sterilisation cycles. No activation is required; simply expose spore ampoule to sterilization process and incubate. Spore ampoules are available in several configurations.

All spore ampoules 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 colour shift.

Biological indicator Spore Strips for monitoring steam processes consist of:

• An inoculated carrier, 6mm x 30mm thread of Bacillus subtilis (Cell Line 35021)
• Primary packaging in glassine envelopes

The Spore Strips are utilised to monitor Steam sterilisation process efficacy. Bacillus subtilis is typically used to monitor low temperature steam processes (100°C -120°C). The Spore Strips are labelled for industrial use only.

Process Steam Strip Dimensions: 6mm x 30 mm
Glassine Dimensions: 30mm x 38mm
Packaging: 100 / Pack

INOCULATED CARRIER SPORE DISCS For Monitoring STEAM

Disc dimensions: 6 mm

Packaging: 100 / Pack

Inoculated carrier Spore Discs and mini Spore Discs for monitoring steam processes consist of:

• An inoculated carrier, 6mm disc of Geobacillus stearothermophilus (Cell Line 7953)
• Primary packaging in bulk

The Spore discs are designed to directly into a device and used to monitor steam sterilisation process efficacy. The Spore Discs are labelled for industrial use only 

Spore Discs will fit into small areas of a device where a standard-sized (6 mm x 30 mm) spore strip cannot be used, such as within a syringe barrel, inside tubing or under a cap.

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

Population: 106
Description: 0.7mL
Packaging: 50/box + 5 negative controls

Excelsior offers spore ampoules for use in monitoring the efficacy of steam sterilisation processes. Spore ampoules are a self contained biological indicator ideal for use in validation of liquid sterilisation cycles. Ampoules may be placed in larger containers such as vials but are also suitable for monitoring non-liquid loads. No activation is required after exposure of the spore ampoule to a sterilisation process. Remove the ampoule post exposure from the steriliser and incubate.

Spore ampoules are manufactured using hermetically sealed Type I borosilicate glass containing a modified Soybean Casein Digest Broth with pH indicator & the specified population of Geobacillus stearothermophilus. Growth is evident by either turbidity and/or a shift in colour.

Spore ampoules are labelled with 24 months of shelf life. Store ampoules under refrigerated conditions (5 ± 3˚C). Spore ampoules are compliant with ANSI/AAMI/ISO/EN and USP where applicable.

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.
