SCBIs & MSCBIs 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 and MSCBIs also offer a shortened incubation period. Traditionally this has been 24 hours, already reduced from 7 days, however Excelsior Scientific is now proud to announce that our SCBIs now offer a rapid readout.

The recovery medium consists of a modified Soybean Casein Digest Broth with pH indicator. Activate for incubation by depressing the cap completely for SCBIs, or squeezing the sides of the MSCBIs and crushing the ampoule. Growth is evident by either turbidity and/ or a colour shift of the media. SCBIs and MSCBIs 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 9mm x 48mm are offered in boxes of 50 units. MSCBIs which are 8.3mm x 45.8mm are offered in boxes of 100 units. Each box is accompanied by a Certificate of Analysis and Instructions for Use.
