SGM Strip

SGMStrip® is a conventional paper strip biological indicator for monitoring steam, low temperature steam formaldehyde, ethylene oxide, dry heat, and gamma radiation industrial sterilisation processes.

SGMStrip® contains bacterial spores on a filter paper carrier sealed within a convenient, peel-open glassine envelope. To use an SGMStrip, simply place the blue glassine envelope inside a product or product package.

This "inoculated package" is placed in a steriliser and processed. Upon removal from the steriliser, the inoculated package is sent to the microbiology laboratory for transfer of the SGMStrip®. The BI is to be aseptically cultured in soybean casein digest medium, and incubated at the appropriate temperature for 7 days.
