The largewells act as undiluted subsamples; the small wells as diluted subsamples.However, no diluent is required.Quanti-Tray/2000’s 97 wells result in a very high counting range (1 to 2,419)and very precise 95% confidence limits. The limitations of multiple-tubefermentation—lots of hands-on time, low counting range and broad 95%confidence limits—become strengths with Quanti-Tray ® and Quanti-Tray/2000:little hands-on time, high counting range and narrow 95% confidence limits.1:1342,419Cost-Effective• 70% less equipment costscompared to membrane filtration• Less than one minute hands-on timereduces labor costs• Media preparation not required• No repeat testing due to cloggedfilters or heterotrophic interference1:101:100diluentsample(no diluent needed)sample1,60015-TubeSerial DilutionQuanti-Tray/2000Quanti-Tray/2000 has 97 wells,resulting in a very high counting rangeup to 2,419 organisms/100 mL.For more information visit www.idexx.com/wateror in the U.S. and Canada, call 1-800-321-0207.Manufactured under one or more of the following U.S. Patents: 4,925,789; 5,429,933; 5,518,892; 5,610,029;5,620,865; 5,620,895; 5,753,456; and 5,780,259.
