Frequently Asked Questions
Q: How many test can be done with one kit?
A: Each kit contains test vials and disposable pipettes and caps for performing 2 tests.
Q: What happens if I add less or too much water?
A: The test is designed as a limit test,as a result is less sensitive to the exact amount of water used in the test. If at least one coliform bacteria is present the test will change color withing 48 hours
Q: What does it means if the vial remains yellow in the first 48 hours but changes color a couple of days later?
A: The reagent in the test vial detect presence of an enzyme produced by coliform bacteria. However the enzyme can be sometime present at very low concentrations from other sources of from dead bacteria. This can cause the solution sometimes to change color after a longer time ( after 4-5 days or even longer). However, if the vial did not change color within the first 48 hours there is no viable (live) fecal coliform bacteria in your water.
