5033 Toxi-ChromoPad

$185.00

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 assay allows the bacteria to grow in direct contact with the toxicants in the sample, eliminating expensive extraction procedures. The endpoint of the assay is an easy to interpret colour reaction. If the sample is toxic, no colour will develop; if the sample is non-toxic, a distinctive blue colour develops around the sample.
