Westbrook, Maine-based IDEXX’s Quanti-Tray system is a USEPA-approved advance in bacterial counting automation that uses Colilert reagent and an automatic sample handling system to produce bacterial counts. The Quanti-Tray Sealer distributes the sample/reagent mixture into the 51-well tray in less than 15 seconds. The sealed tray is incubated 24 hours and colored wells counted. A table converts the number of yellow wells to a coliform count and the number of yellow/fluorescent wells to an E. coli count.
