Modern Water is expert in the design, development and provision of analytical instruments and technologies for monitoring toxicity in water, soil, food and industry. Our systems use bioluminescent bacteria to perform biosensor testing that detects the presence of toxic substances.
Biosensor tests using bioluminescent bacteria have been in use for more than 30 years and their capability in detecting toxic substances is well understood. They use the principle that certain strains of bacteria emit light when healthy. When they are exposed to toxic substances, the amount of light emitted reduces. The greater the toxicity of the sample, the lower the light emitted. Measuring changes in light between healthy bacteria and bacteria exposed to toxic substances will therefore indicate the presence of a toxin in a sample.
Our Microtox® LX toxicity test system is the industry standard for laboratory-based rapid toxicity screening and analysis. Microtox® FX is the portable, acute toxicity analyser used with the Microtox® technology. Modern Water’s new Microtox® CTM is a site-based, broad range Continuous Toxicity Monitor (CTM).
Our range of toxicity testing technologies is both industry-leading and ground-breaking. For a full list of scientific papers written about our Microtox® technology visit the Microtox Bibliography.
Deliberate and accidental contamination events
Drinking water monitoring
Industrial process water
Mining wastes, soil and water
Monitoring of rivers, lake, reservoirs, seawater, groundwater/natural attenuation
Potable water at point of use or in the distribution network
Modern Water’s new Microtox® CTM is a site-based, broad range, Continuous Toxicity Monitor (CTM). It continuously measures the chemical toxicity of a water source, giving instant indication of water health.
Microtox® CTM is a fully automatic instrument that offers a 4-week, autonomous operating cycle and requires a low level of skill for both operation and maintenance.
Microtox® CTM makes fully automatic, continuous, on-line testing a reality. It has broad range detection capabilities that provide rapid early warning of contamination by several thousand known chemicals. This enables containment measures to be actioned in time to protect against serious contamination events.
A major advantage over most analytical methods is that Microtox® CTM is able to detect contaminants whether or not there is prior knowledge of the potential source or nature of contamination. Other on-line toxicity monitors take intermittent samples and provide only one test result in typically 15-30 minutes. This means that brief events may be missed and leads to a high incidence of false alarms. Microtox® CTM takes one measurement every ten seconds, significantly reducing the risk of false alarms.
Real-time and truly continuous monitoring
4-week, autonomous operating cycle
No manual intervention except for monthly maintenance
Automatic diagnosis of system faults
Remote control, data analysis and troubleshooting
Detects thousands of chemical compounds with lower levels of detection than most other biosensor systems
The Microtox® LX analyser is a laboratory-based, temperature-controlled luminometer, self-calibrating luminometer that measures acute toxicity.
Microtox® LX is a biosensor-based measurement system that uses bioluminescence technology to monitor for either accidental or deliberate contamination of both water supplies and waste water. With over 2,900 instruments sold worldwide, the Microtox® toxicity test system is the industry standard for rapid toxicity screening and analysis.
Microtox® rapid toxicity detection is an in vitro test system that uses bioluminescent bacteria for the detection of toxicity in water and is used as a screening system to detect the relative toxicity of a sample. Applications include the testing of samples containing biological toxins, industrial effluent, industrial process waters, municipal effluent, drinking water, ecotoxicological samples, hazardous waste, soil, sediments, storm water and medical products for bio reactivity.
Biological earning warning system sensitive to more than 2,700 simple and complex chemicals allows the protection of drinking water supplies from accidental or deliberate contamination.
Test results highly correlated with other widely accepted toxicity test methods helps to ensure compliance with regulatory and effluent permit standards in wastewater applications.
Proven – Numerous independent scientific studies have documented Microtox’s performance as an effective toxicity screening tool in a wide array of applications
Increased Sensitivity – The use of a new proprietary, fully dynamic photomultiplier increases the sensitivity of the instrument.
Fast, Reliable and Reproducible Results – Results Available in as little as 15 minutes after initial sample preparation.
The instrument’s new automatic color correction feature adjusts test results based on the sample’s turbidity.
Actively cooled sample and read wells enable more precise and consistent readings.
Cost effective – A low cost toxicity test that requires small sample volumes.
Manufactured in a certified ISO 13485 quality system with 100% lot traceability.

Microtox FX ™ is a simple, rapid, extremely responsive, portable water quality test system.
Designed for acute toxicity screening and adenosine triphosphate (ATP) testing, Microtox® FX uses bioluminescence technology to screen for contamination in instances of drinking water emergencies and chemical spills into water systems. Microtox® FX is a portable toxicity analyser.
The Microtox® FX instrument has a combined detection capability that provides a very sensitive and rapid test to detect two of the most probable classes of agents, pathogens and toxic chemicals that may accidently or intentionally contaminate drinking water or wastewater. Microtox® FX's acute toxicity and ATP detection capabilities make it the ideal instrument for rapidly and accurately assessing if the quality of drinking water, from the source to the tap, has been affected by an incident.
Test sensitive to more than 2,700 different simple and complex chemicals
Results available in 20 minutes
Excellent correlation with HPC methods
Microbial detection level in drinking water -100 cfu/mL
