Rapid Water Toxicity Testing Analyzer
Microtox LX Rapid Toxicity Analyzer
Rapid laboratory screening for acute toxicity in water and environmental samples
The Modern Water Microtox® LX is a laboratory-based acute toxicity analyzer designed for rapid screening of drinking water, wastewater, industrial effluent and environmental samples. Building on the proven Microtox M500 technology, the LX uses a bioluminescence-based measurement system to detect the overall toxic effect of a sample rather than requiring the operator to identify individual contaminants. Results available in 15 minutes after initial sample preparation, supporting faster response to contamination events and routine toxicity monitoring.
Microtox LX functions as a biological early-warning system and is sensitive to more than 2,700 simple and complex chemicals. Its results correlate closely with widely accepted toxicity test methods, making the instrument useful for environmental monitoring, wastewater compliance, process control and research applications.
Bioluminescence technology for broad-spectrum toxicity detection
Microtox LX measures changes in bioluminescence to evaluate the relative toxicity of a sample. A proprietary fully dynamic photomultiplier provides increased measurement sensitivity, while actively cooled reagent, incubation and read wells help maintain controlled test conditions for precise and reproducible measurements.
Because the system measures biological response, it can provide a rapid indication of toxicity from complex mixtures and unknown contaminants. This makes Microtox LX particularly useful when conventional chemical analysis alone may not provide an immediate picture of the combined toxic effect of substances present in a sample.
Automatic color correction for challenging samples
An integrated color-correction function can compensate for variations in sample color and turbidity that could otherwise influence the optical measurement. The feature can be enabled or disabled as required, expanding the analyzer's usefulness across diverse water and environmental samples.
Applications
Drinking water monitoring
Water utilities can use Microtox LX to screen source water, water during treatment, finished water before distribution and samples collected throughout the distribution system. Its rapid biological response can provide an early warning of accidental or deliberate contamination and help operators determine when further investigation or corrective action is required.
Wastewater and industrial effluent
Wastewater facilities can incorporate rapid toxicity testing into pretreatment and process-control programs to identify potentially toxic influent streams before they disrupt biological treatment. Testing can also support effluent monitoring, help reduce the risk of permit violations and provide useful information for controlling treatment costs and maintaining stable plant operation.
Environmental and industrial testing
Microtox technology has been applied to industrial process water, mining samples, drilling fluids and muds, marine water, sediments, stormwater, solid-phase materials, pharmaceutical and medical products, food-processing water, food-packaging materials, and personal-care and household chemical analysis.
Designed for efficient laboratory workflows
The Microtox LX incorporates a 7-inch color touchscreen tablet with Microtox LX software, along with USB, Wi-Fi and Bluetooth connectivity. Test results can be stored for future reference or transferred using a USB drive. The system supports standard, customizable and quality-control protocols, helping laboratories adapt testing to different monitoring and research requirements.
Standard and customizable test protocols
Microtox LX software includes protocols for Basic Toxicity, Comparison, Confirmation, Screening Toxicity, SOLO Screening, Solid Phase/Basic Solid Phase and Whole Effluent Toxicity (WET) testing. Supported standardized methods include ASTM D5660, DIN 38412 and ISO 11348-3. Parameters within standard protocols can also be modified for application-specific testing, while zinc and phenol protocols are available for quality control.

Q&A
Does Microtox LX identify the specific chemical contaminating a sample?
No. Microtox LX is a toxicity-screening system that measures the biological response to a sample. It indicates the presence and relative level of toxic effects rather than identifying individual chemical compounds. Positive or unexpected results can therefore be used to trigger additional targeted chemical analysis.
How quickly can Microtox LX provide toxicity results?
Results can be available in as little as 15 minutes after initial sample preparation, making the system suitable for situations where laboratories and water-treatment operators need a rapid indication of potential toxicity.
Can Microtox LX test samples other than drinking water?
Yes. Applications include wastewater, industrial effluent, process water, marine water, mining samples, stormwater, sediments, solid-phase materials, drilling fluids and various pharmaceutical, medical and industrial samples.
How does Microtox LX handle colored or turbid samples?
The analyzer includes an optional automatic color-correction function that adjusts results to compensate for variations in sample color and turbidity. The function can be switched on or off according to the testing requirement.
Can laboratories modify the supplied test protocols?
Yes. The Microtox LX software includes established test protocols while also allowing parameters within standard protocols to be modified for application-specific testing requirements.
Which recognized toxicity-testing standards are supported?
The Microtox LX software supports established methods including ASTM D5660, DIN 38412 and ISO 11348-3, in addition to several screening, comparison, confirmation, solid-phase and Whole Effluent Toxicity protocols.
