We recently received a question from 'Kerry' who asked, "How high will this read? How many cfu/100 ml"
Good afternoon, Kerry, and thank you for your inquiry.
The product you asked about (EZ Coliform Cult (MUG) Test) does not provide a numeric value of coliform bacteria detected. Instead, it serves as a presence/absence test showing whether or not a water sample contains 1 cfu/100 ml.
We do, however, know of a test called 'CBT' that provides users with more quantitative results by indicating that a water sample contains coliform bacteria contamination in one of several ranges. You can obtain more information on the test by visiting www.aquagenx.com.
