IDEXX Quanti-Tray System is an innovative advance in the bacterial enumeration. Quanti-Tray eliminates subjective colony interpretation and time-consuming confirmation. It delivers semi-automated quantification methods based on the Most Probable Number (MPN) model to provide easy, rapid and accurate bacterial counts.
- Provides easy, rapid, and accurate bacterial counts.
- Detects down to one organism per 100 mL.
- Quanti-Tray and Quanti-Tray/2000 are used when quantifying coliforms, E. coli, enterococci and Pseudomonas aeruginosa.
- The Quanti-Tray System delivers semiautomated quantification methods based on the Most Probable Number (MPN) model.
Quanti-Tray
With Quanti-Tray, a 100 mL sample is divided into 51 wells. The Most Probable Number (MPN) approach is used to determine the number of bacteria in the original sample. Automation minimises hands-on time and maximises throughput (up to 4 samples per minute). The relatively large number of wells provides a high counting range of 1â¢ÃöâÃÃâè200 (without dilutions) and very tight 95% confidence limits.
Quanti-Tray/2000
The Quanti-Tray/2000 is based on the same statistical model as the traditional 15-tube serial dilution. With the Quanti-Tray/2000, the sample is automatically divided into the proper portions when sealed by the Quanti-Tray Sealer PLUS. The Quanti-Tray system does not require the use of test tubes, Durham tubes, or any dilutions. By automatically distributing the sample into 97 wells of 2 different sizes, Quanti-Tray/2000 yields a counting range of 1â¢ÃöâÃÃâè2,419 with a far better 95% confidence limit than a 15-tube serial dilution.
Quanti-Tray Sealer Plus
The Quanti-Tray Sealer PLUS is the next generation sealer in the Quanti-Tray system. The sealer makes quantification with Quanti-Tray and Quanti-Tray/2000 possible while saving time and improving laboratory efficiency. Features include a 2â¢ÃöâÃÃâè3 minute warm-up time, faster sealing of trays, energy efficiency, and an access panel that makes cleaning easy.
How to use
- Add sample/reagent to tray.
- Seal tray in Quanti-Tray Sealer PLUS.
- Incubate, count positive wells, and refer to appropriate MPN table.
