ToxTrak„¢ Toxicity Test Speeds Sample Evaluations

In as little as 45 minutes, ToxTrak allows you to evaluate toxicity in a sample. Applicable to both drinking water and wastewater, ToxTrak measures and compares the toxicity of a sample to a baseline using either indigenous biomass or stock bacteria cultures.

Colorimetric Method

Toxicity is monitored using several methods, such as growth, specific enzyme activity, bioluminescence, and respiration. These methods may require lengthy incubation times, centrifugation, solvent extraction, laborious colony counting procedures, and expensive equipment. With the ToxTrak Toxicity Test, you use a simple colorimetric method to determine the inhibitory effects of a waste stream on bacteria. With a photometer, you can monitor large numbers of samples quickly and inexpensively.

Economical Alternative to Bioassays

Cut costs in your laboratory by using ToxTrak to screen for potentially toxic influents and effluents. Or use it to identify dilutions for long-term bioassays. Long-term bioassays can require two to seven days to complete and are costly to perform.

ToxTrak is an inexpensive alternative that has results comparable to respirometric methods measuring dissolved oxygen consumption. You can use ToxTrak to screen influent and effluent and/or process waters. 

ToxTrak is also a useful tool for evaluating fluctuations in drinking water quality caused by intentional or accidental contamination.
