Self-Contained Biological Indicators (SCBI)
Rodwell offers Self-Contained Biological Indicators (SCBI) for monitoring steam sterilisation processes in spore population levels of 105 and 106.
Each SCBI unit consists of a plastic vial with a cap, a crushable glass ampoule with recovery media, and a disc inoculated with spores. SCBIs 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 and SCBIs offer a shortened incubation period. The recovery medium consists of a modified Soybean Casein Digest Broth with pH indicator. Activate for incubation by depressing the cap completely for SCBIs and crushing the ampoule.
Growth is evident by either turbidity and/or a colour shift of the media. SCBIs 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 (15ºC – 30ºC) conditions.
SCBIs which are 12mm x 61mm are offered in boxes of 50 units. SCBIs are accompanied by a Certificate of Analysis and Instructions for Use. Rodwell SCBIs are compliant with ANSI/AAMI/ISO/EN 11138-1 and USP where applicable.
