Notice: as of November 1, 2011, SGMStrip has become MesaStrip. No change has been made to the manufacturing process or location; this is a change in name only.

MesaStrip is a conventional paper strip biological indicator for monitoring steam, low temperature steam formaldehyde, ethylene oxide, dry heat, chlorine dioxide, and gamma radiation industrial sterilization processes. MesaStrip contains bacterial spores on a filter paper carrier sealed within a convenient, peel-open envelope.

To use a MesaStrip, simply place the envelope inside a product or product package. This “inoculated package” is placed in a sterilizer and processed. Upon removal from the sterilizer, the inoculated package is sent to the microbiology laboratory for transfer of the MesaStrip. The BI is to be aseptically cultured in soybean casein digest medium, and incubated at the appropriate temperature for 7 days.
