Quanti-Tray® and Quanti-Tray 2000® From IDEXX

Combines the rapid and easy-to-use technology of Colilert® and Colisure® technology reagent with the added benefit of enumerated results. To conduct the test: add reagent to the sample; pour the sample reagent/mixture into a Quanti-Tray; seal the tray and incubate. Quanti-Trays are sterile and disposable trays. Quanti-Tray contains 51 separate wells and counts (Most Probable Number) up to 200 CFU/100 mL. Quanti-Tray 2000 contains 96 wells and counts up to 2,419 CFU/100 mL without any dilutions. Sealing is accomplished through the use of the specially designed sealer. Results are available in 18 or 24 hours.

Quanti-Tray indicates the quantity of coliform bacteria by the number of wells that turn yellow or magenta. Fluorescent wells indicate the quantity of E. coli. A simple MPN table converts well counts to a Most Probable Number. Results are both presumptive and confirmatory — no additional testing is required.

Simple Test Procedure
• Less than 2 minutes hands-on time
• Minimizes dilutions
• No pipetting required
• No media preparation

Easy Interpretation of Results
• No subjectivity (sheen/atypical, overlapping)
• Heterotrophic interference minimized
• No confluent growth
• Colony counting eliminated

Accurate
• Detects down to 1 CFU/100 mL
• More precise than 5 or 10 tube MPN
• Accuracy and precision comparable to MF
