Attest™ Super Rapid Steam Biological Indicator 1491
24 Minute Results - Gravity Displacement Steam - 132°C and 135°C - Blue Cap - Box of 50

The Attest™ Super Rapid Readout Steam Biological Indicator 1491 is a self-contained biological indicator for monitoring gravity displacement saturated steam sterilization processes at 132°C (270°F) and 135°C (275°F). Attest is a Solventum brand, formerly 3M, and the 1491 was previously sold as the 3M Attest Super Rapid Readout Steam Biological Indicator. When incubated in an Attest Auto-reader 490 or 490M, the 1491 gives a fluorescent result in 24 minutes, so facilities can confirm steam sterilization cycle results quickly for both routine monitoring and qualification testing.

Each indicator contains a spore carrier with Geobacillus stearothermophilus spores and a sealed glass ampoule of bacteriological media. After the sterilization cycle, the indicator is activated and incubated. The 1491 conforms to ISO 11138-1:2017 and ISO 11138-3:2017. Blue colour-coded caps make the 1491 easy to identify, and a UDI-compliant 2-D barcode allows the GTIN, lot code and use-by date to be captured with a handheld scanner. The BI tray, QA certificate, IFU, packaging and labels are recyclable. Each box contains 50 biological indicators.
