iTOXcontrol is a multifaceted and sophisticated online water toxicity monitoring analyzer. It features an integrated and automated system for cultivating Vibrio fischeri bacteria. All the measuring process complies with ISO 11348 part1 and is EPA validated. Data can be transmitted to an external system to facilitate alarm monitoring and modeling decisions. The compact design is space-saving, and its low maintenance requirement with a cycle of only 1 hour every 2 weeks showcases efficiency. Ideal for a range of applications, this analyzer provides real-time data through TCP/IP communication, delivering a dependable and cost-effective solution for continuous water quality monitoring.
The iTOXcontrol technology is based on a bioassay for assessing the toxicity of water. It employs the bioluminescent bacterium Vibrio fischeri, that is internally cultivated, which emits light as a natural response to stress, particularly in the presence of toxic substances. In the test, water samples are exposed to Vibrio fischeri; the reduction in bioluminescence is measured using a luminometer. The greater the reduction in light emission compared to a control sample, the higher the toxicity of the tested sample. iTOXcontrol provides speed, simplicity, and sensitivity and is a valuable tool in environmental monitoring, industrial discharge assessments, and regulatory compliance evaluations, providing rapid indications of the overall toxicity of water samples.
iTOXcontrol is an online analyzer for water toxicity monitoring, featuring automated Vibrio fischeri cultivation. Its compliance with ISO 11348 part 1 provides a true and reliable real-time water toxicity monitoring.
The TOXmini is a state-of-the-art portable water toxicity analyzer, perfect for both laboratory and field applications. Designed for simplicity and precision, it automatically measures the luminescent effect of the Vibrio fischeri, quickly indicating potential toxicity in the water sample being tested.

The luminescent bacteria used for the tests are Vibrio fischeri species, also known formally as Photobacterium phosphoreum. Vibrio fischeri is a marine organism, and consequently the fluid for these bacteria must be maintained at a salt concentration of 2%. Freeze-dried bacteria should be stored at -20°C in a freezer. In addition, during shipping/transportation, lyophilized bacteria must remain below 0°C. The cultures of luminescent bacteria can be stored by cooling in the luminescent bacteria test equipment at 5°C for one week without losing their sensitivity to pollutants.
The TOXmini, a user-friendly hand-held system designed to perform toxicity measurements on a wide range of samples and applications, has a memory capacity of 2000 points. By automatically measuring the luminescent effect of Vibrio fischeri, it provides a clear indication of toxicity in the test sample. This device is suitable for laboratory use. It can be combined with an optional cooling unit, and thanks to its built-in rechargeable batteries can be operated in the field. The data stored on the TOXmini can be downloaded to a PC using the appropriate connecting cable.
