Twenty-four minute readout Biological Indicator for 132°C (270°F) 3 or 4 minute and 135°C (275°F) 3 minute Dynamic-Air-Removal Steam Sterilization cycles (Brown Cap). 50 each/box.
The 3M™ Attest™ Super Rapid Readout Biological Indicator 1492V 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) dynamic‑air‑removal (pre‑vacuum and steam-flush pressure-pulse (SFPP)) steam sterilization processes when used in conjunction with the 3M™ Attest™ Auto‑reader 490 or the 3M™ Attest™ Auto-reader 490H having software version 4.2.7 or greater. The self‑contained design includes a 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 brown 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.
