Microbium MPN Analyser

Microbium MPN Analyser is a fully automated microorganism counter for quantitative detection of Escherichia coli and coliform bacteria in drinking water, wastewater and other liquid samples.

Microbium MPN Analyser can be used for the quantification of pathogenic E. coli and coliform bacteria in drinking water, wastewater and other liquid samples.

The analyser uses a unique technology called multiplex polymerase chain reaction (PCR) to detect and quantify specific DNA fragments which are unique to E. coli or coliform bacteria. The PCR reaction products are detected by fluorescence resonance energy transfer (FRET). The reaction conditions are optimized so that only one target species will be amplified at a time, while other non-target species are suppressed.


Faster results

Results are ready within 30 minutes

Less operator influence on results

There is less room for operator error since no manual dilution steps are required

Improved precision

Automatic dilutions reduce variability between samples

The Microbium MPN Analyser can be used with any existing sample or reagent tube or cartridge. It is designed to be simple to use with minimal training required. It takes only seconds to setup and start testing samples – no need to calibrate or maintain!

The MPN Analyser is based on the Multiplex Polymerase Chain Reaction (PCR), a method that uses specific primers to amplify DNA fragments. The resulting fragments can then be detected using real-time PCR, which allows the detection of specific targets within just a few minutes. This technology has been used in clinical diagnostic laboratories for more than 20 years, but until now it has not been available to the water industry.

The Microbium MPN Analyser is designed for efficient, high throughput analysis of samples from drinking water treatment plants (DWTP), wastewater treatment plants (WWTP), potable water distribution systems, stormwater runoff and groundwater sources.
