Product Description

AMT-I-B-004 Rapid Bac IRB (7 ML)

Iron-Related Bacteria (IRB) can be found in potable water, well water and industrial water. IRB’s are known to cause discoloration of water and also deposits of iron on pipes in industrial water systems. AMT RAPID BAC IRB Test provides a fast and reliable method for the detection of IRB. Diagnostic reagents are preserved in a self-filling vacuum ampoule with extended shelf-life. Bacterial levels are represented as CFU/mL (colony formation unit per milliliter). Each box includes 30 stand-alone tests.


IRB’s oxidize ferrous to ferric ion, which is precipitated as ferric hydrate. Iron may be obtained from the pipe itself or from the water. The amount of ferric hydrate deposited is usually very large in comparison with the amount of bacteria present. Some bacteria belonging to this group which do not oxidize ferrous iron may, nevertheless, indirectly cause it to be dissolved or deposited. During growth, they either liberate iron by utilizing organic radicals to which the iron is attached or they alter environmental conditions to permit the solution or deposition of iron.
