Enquiry Item
The EZ-ATP monitors total bacterial and pathogen load in water by measuring portions of ATP (adenosine triphosphate) of any type of bacterial microorgnism presnt in the water sample. These may include fecal coliforms such as E.coli, sulphate reducing bacteria, nitrifying bacteria or Legionella. The analyzer can be used as an Early Warning System in various applications with focus on water safety, when high ATP values indicate a potential risk in surpassing a threshold value of mircooganisms in the past or in the near future.



  • Complying with internationally accredited ASTM D4012-81 standard test method
  • Rapid measurement: 10 minutes (including lysis)
  • No delay between sample take-off and measurement
  • No bias from the composition of the growth medium such as with plate counting
  • Complete ATP recovery: detection of intracellular, extracellular and total ATP
  • Low cost of analysis relative to a large number of results
  • Smart functions: automatic calibration and cleaning


  • Analysis method: Determination of adenosine triphosphate by means of chemiluminescence reaction using luciferin and luciferase (Standard method ASTM D4012-81)
  • Measuring ranges: 0.5-200pg/ml or 0-400 pM ATP (Higher ranges are available on request)
  • Cycle time: 10-15 minutes (including lysis)
  • Calibration: Factory calibrated (2-point), typically 45 minutes
  • Cleaning: Automatic, free adjustable sequence
