Colitag iMPNplate 1600 water test system

Thursday, 02 May, 2013 | Supplied by: Pacific Laboratory Products



The Colitag iMPNplate 1600 is a definitive system for measuring microbial contaminants in water with what is claimed to be the widest testing time window in the industry: 16 to 48 h. The system offers greater selectivity for total coliforms and E. coli with the help of selective growth inhibitor of Aeromonas and Pseudomonas strains.

The selective dehydrated media formula automatically resuscitates and detects chlorine-injured bacteria, resulting in a complete, highly sensitive tool for regulated site testing.

The Colitag is an easy-to-use device for enumerating microorganisms in a liquid sample. It is a modern approach to the traditional method of serially diluting the sample on a statistical model to produce the most probable number (MPN) index. The time-consuming and labour-intensive process of serial tube dilutions is done by the patented plate system of five duplicate wells in 10, 1 and 0.1 mL well volumes, with a 16th well for collecting the remaining sample.

Results readings are direct for coliforms and definitive for E. coli with the use of a UV light source. Tests using the iMPNplate-1600 offer a high degree of sensitivity, with a detection limit ranging from 0-1600 MPN per 100 mL sample within the standard reading window. The device is stand-alone in set-up and requires only an incubator and UV light source to perform the test.

The Colitag is US EPA approved for use in MPN format.
