Attest™ Auto-readers & Biological Indicators For Steam

Attest 1292-S Rapid Readout Biological Indicator For Steam

The Attest 1292 is a self-contained biological indidcator designed for validation and routine monitoring of industrial steam sterilization processes, when used in conjunction with teh 3M Attest Model 293 or Model 290 Auto-readers. The Attest 1292-S is comprised with a standardized population of Geobacillus stearothermophilus Atcc 7953 spores, a non-woven spre strip support, a glass ampoule containing recovery media which includes a pH indicator and fluoregenic indicator, a plastic cap with filter, and a plastic sleeve.

The 3M Attest 293 and 290 Auto-readers are designed to incubate the Attest 1292-S at 60ºC ± 2ºC and automatically read the fluorescent response of the Attest 1292-S with a final end point reading at 3 hours. The Attest 293 and 290 Auto-readers are also designed to allow for further incubation of the Attest 1292-S to look for a media color change. Since media dry-out will occur upon extended incubation in the Auto-reader (typically 2-3 days) transfer of the indicators to humidified incubators will be required to insure adequate growth media during longer incubation periods.
