SimPlate for Total Coliform & E. coli Color Indicator (CEc-CI) method is used for the detection and quantification of the Total Coliform and E. coli populations. It is based on Binary Detection Technology (BDT) which equates the presence of Total Coliform to the presence of a color change in a medium and E. coli is detected by the presence of a blue fluorescent color change in the medium due to the action of the enzyme and Β-glucuronidase. The medium/sample mixture is dispensed into a SimPlate device, and incubated for 24-28 h. The Total Coliform and E. coli count is determined by counting the wells with changed color and referring to the SimPlate Conversion Table. Colored wells indicate the presence of Total Coliforms, and colored wells that fluoresce indicate the presence of E. coli. The SimPlate device is packaged separately.

Características y beneficios
- Total Coliform and E. coli results are available from a single plate. Proprietary chromogenic media and patented plating device with isolation wells combine to produce easily counted results. Because results are not dependent on gas formation, results are more easily interpreted than tube or film-based methods.
- While other plating methods require duplicate plating of samples, and the standard MPN method requires multiple dilutions and at least nine tubes of media, SimPlate has been validated to provide equivalent results with just a single plate. Combined with the reduction of necessary sample dilutions, made possible by the broad counting range of the plate (1-738), SimPlate reduces the volume of media and number of tests required for each sample, helping to reduce overall testing costs.
