3M Attest Mini Auto-Reader - 490M

3M Attest Mini Auto-Reader 490M is a compact benchtop biological-indicator reader that incubates and analyzes compatible Attest Super Rapid Readout BIs for steam sterilization. It is built for point-of-care and satellite sterile processing rooms that need fast, objective BI results to release instruments with confidence. Clinics, dental offices, ambulatory surgery centers, and satellite SPD workstations use the 490M after steam cycles to verify that sterilization parameters were adequate and that loads are safe to put back into service. Two independent wells read indicators in parallel, and clear status lights guide the user from incubation to result so staff can keep workflow moving.

Results are available in about 24 minutes with Attest 1492V Super Rapid Readout BIs, which helps teams decide quickly whether to quarantine or release a load. The reader sets up in minutes, requires only AC power, and features a small footprint that fits on crowded counters. Use it wherever quick BI confirmation, documentation, and compliance are priorities.
