“The Attest 190 auto-reader is designed to read the fluorescence produced by positive Attest 1292E rapid readout biological indicators. It detects the presence of an active Bacillus stearothermophilus ATCC 7953 sporeassociated enzyme, alpha-glucosidase, by reading a fluorescent product that is produced when the enzyme converts the non-fluorescent substrate, 4-methylumbelliferyl-alpha-D-glucoside, in the media vial. The fluorescence indicates the presence of active Bacillus stearothermophilus ATCC 7953 spore-associated enzyme and a steam sterilization process failure. Nonfluorescence indicates inactivation of the enzyme and an adequate steam sterilization process. A sterilization process failure is observed by a red light (“ ”). An adequate sterilization process is observed by a green light (“-”).” Specifications: Condition: Used Type: Biological Indicator Autoreader Make: 3M, Attest Series: Autoreader Model: 191 Serial: 201183 Input: 240VAC, 0.315A Accessories: Nil Weight: 2.2kg Replacement price on this item is approximately AUD$ The unit is sold with a 30 Day Warranty.
