Hardware Disclaimer
The 3M™ Attest™ Mini Auto-reader 490M hardware specifications are subject to

INTENDED USE
The 3M™ Attest™ Rapid Biological Indicator System provides rapid, reliable
monitoring of steam and vaporized hydrogen peroxide sterilization processes
performed in health care facilities� The system is comprised of biological indicators,
challenge packs, and incubator/readers�
The 3M™ Attest™ Mini Auto-reader 490M is designed to incubate and
automatically read 3M™ Attest™ Biological Indicators 1295, 1491, and 1492V at
60°C for a final negative fluorescence reading at 24 minutes� The 3M™ Attest™
Mini Auto-reader 490M is also designed to allow for further incubation of
3M™ Attest™ Super Rapid Readout Biological Indicators, catalog numbers 1491 and
1492V, for a final negative, visual pH color change result at 24 hours and 48 hours,
respectively� This further incubation is optional and not intended for routine use�
A positive fluorescent result or a visual pH color change indicate a sterilization
process failure� However, due to the high sensitivity of the fluorescent result, there
is no advantage to continuing to incubate processed 3M™ Attest™ Biological
Indicators once the fluorescent result has been documented�
Other biological indicators (BIs) are not compatible with this device and cannot be
used�
INDICATIONS FOR USE
