A microplate toxicity bioassay to determine acute and chronic toxicity in water, effluents, and other liquids.The Toxi-ChromoTest^TM procedure exposes the bacteria to the toxicants in the sample for a short (90-minute) incubation period. After the incubation period, a chromogenic substrate is added. If the sample is toxic, no colour will develop and if the sample is non-toxic, a distinctive blue colour quickly develops. The kit provides a clear, completely objective measurement of the toxicity of the sample by a simple visual qualitative evaluation of the colour obtained, or quantitatively by spectrophotometry using a micro-plate reader.

The Toxi-ChromoPadTM bioassay uses a novel mutant of the bacterium E. coli as the test organism. This bacterium was selected specifically for sensitivity to a wide range of toxic substances and is well adapted for acute sediment toxicity testing.

The SOS-ChromoTest kit is based on a novel genetically engineered E.coli, which measures the primary response of a cell to genetic damage. In just a few hours, the kit provides a clear, completely objective measurement of the genotoxicity of a sample by a simple visual qualitative evaluation of the degree of DNA damage the cell experiences by observing the colour obtained. A more quantitative value may be obtained by spectrophotometry using a micro-plate reader. The SOS-ChromoTestTM analyses are highly correlated with the Salmonella `Ames Test` for certain materials.

A convenient test for quantitative measure of total coliforms and E. Coli bacteria. The test is designed to   meet regulatory guidelines and quantifies density of target bacteria, coliforms and E. Coli, ranging from 5 to 5,000 colony forming-units (cfu) per 100 mL sample, without dilutions. Monitoring surface and drinking water for dangerous bacteria is needed to prevent illness or disease. Since it is not practical or technically feasible to monitor for all pathogens in our water, the microbiological quality of drinking water is evaluated based on indicator organisms such as total coliforms and E. coli.
