Flo provides a revolutionary mail-in water testing service with same-day test results. Offices wanting the protection of 3rd party lab results will no longer need to wait 7 days for results. After overnight shipping, results will be provided the same day. Flo accomplishes this by using the most advanced and accurate testing technology available, Flow Cytometry. This method utilizes laser light and fluorescence to count the exact number of bacteria per mL in a sample. The Flo test kits come complete with everything needed to test and are available with (90000 series) and without (70000 series) FedEx overnight shipping included. And, of course, each kit includes complimentary consultations with our leading water safety team.
