Understand the microbial load within minutes with ATP Test Kits
Bug bottles (serial dilution media or culture media) tell you how many of a certain type of microbe (SRB) consumed the food source present. What they don’t tell you is how many are capable of consuming that food source but didn’t under the specific testing conditions. If you only test for SRB using bug bottles and subsequently design your biocide programs based on these numbers, there is a risk of drastically underestimating the microbial load, ultimately setting up the treatment program to fail.
LifeCheck ATP Test Kits can be used to identify how many living microbes are present in your sample. This is important when considering biocide programs as they are non-selective, meaning they don’t only kill the bad guys – they kill ‘em all. Because ATP quantifies all the living microbes in a sample, not just the bad guys, ATP testing can be used to:
- evaluate biocide programs
- screen source waters
- design effective treatment programs
