Four-hour, green cap, Rapid Readout Biological Indicator for EO Sterilization (50/box)
The ISO 11138-1:2017 and ISO 11138-2:2017 compliant 3M™ Attest™ Rapid Ethylene Oxide Biological Indicator, 1294, is a self-contained biological indicator (BI) that consists of a Bacillus atrophaeus spore strip and a sealed glass ampoule with growth media. The spore strip and media ampoule are contained in a plastic vial topped with a green color-coded cap which includes a chemical process indicator on top.
When processed, the chemical process indicator turns from reddish-brown to green. After the ethylene oxide sterilization process, the BI is activated to join the growth media with the processed spore strip. The BI is incubated in a 3M™ Attest™ 390G Auto-reader for a final fluorescent result at 4 hours.
