The 3M™ Attest™ Super Rapid Readout Biological Indicator 1491 is a self-contained biological indicator specifically designed for rapid and reliable qualification testing and routine monitoring of 270°F (132°C) and 275°F (135°C) gravity-displacement steam sterilization processes when used in conjunction with the 3M™ Attest™ Auto-reader 490 or the 3M™ Attest™ Auto-reader 490H with software version 4.2.7 or greater. The self-contained design includes a spore carrier with spores of Geobacillus stearothermophilus and a media ampoule containing bacteriological media. The spore carrier and media ampoule are contained in a plastic vial topped with a blue cap. A chemical process indicator which changes from pink to light brown or darker upon exposure to steam is located on the top of the cap.
After processing, the biological indicator is activated and incubated in the 3M™ Attest™ Auto-reader. A final negative reading after the specified incubation period indicates an acceptable sterilization process. A 24-minute result is provided when incubated in Model 490 or 490H Auto-readers having software version 4.2.7 or greater.

My product has 3 parts on the registration number and I can't find all 3 on the approved website for List N. Why?
The first 2 parts of the EPA Registration Number are the primary numbers and represent the primary registration. Since different companies sell products with the same chemical composition and efficiency, only 1 brand or product name receives the primary number. The third part represents the distributor of the primary registration and is still on List N and is proven effective against SARS-CoV-2 (COVID-19).
