Mini Self-Contained Biological Indicators (MSCBI)
Each SCBI , MSCBI & RSBCI unit consists of a plastic vial with a cap, a crushable glass ampoule with recovery media, and a disc inoculated with spores. SCBIs, MSCBIs and RSCBIs are ideal for use in monitoring sterilisation processes in place of traditional Biological Indicator strips, however there is no need for aseptic transfer of the BI to culture media. SCBIs & MSCBI s also offer a shortened incubation period by comparison (24-48 hours rather than 7 days), with RSCBI s offering the fastest incubation at 10 hours.
The recovery medium consists of a modified Soybean Casein Digest Broth with pH indicator. Activate for incubation by depressing the cap completely on SCBI s or squeezing the sides for MSCBI s and crushing the ampoule.
Growth is evident by either turbidity and/ or a colour shift of the media. SCBIs, MSCBIs & RSCBIs are labelled with the shorter shelf life of the two components; the inoculated disc and ampoule which have independent expiration periods. Store under room temperature (15˚C – 30˚C) conditions.
SCBIs which are 12mm x 61mm are offered in boxes of 50 units. MSCBI s & RSCBI s which are which are 8.4mm x 45.5mm are offered in boxes of 100 units. Each box is accompanied by a Certificate of Analysis and Instructions for Use. Excelsior SCBI s have FDA clearance and are compliant to ANSI /AAMI /ISO /EN 11138-1 and USP where applicable.
