Most Probable Number Demo
The most probable number (MPN) test method estimates the number of indicator bacteria that is most likely present in a water sample. This demo will show how to conduct a MPN test using a Hach Pathoscreen Test Kit.
Multiple samples (1-10 mL) of the same water to be tested are added to a culture media in sterile tubes and incubated at a particular temperature for a fixed time (usually 24 hours). By counting the number of tubes showing a positive result
and comparing with a standard table, a statistical estimate of the most probable number of bacteria can be made. The results are reported as MPN per 100 mL.
