AZF848522 Microtox® FX Test System, No SOLO by Modern Water

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 the portable toxicity analyser used with the Microtox® technology

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.

• Biological early warning system sensitive to more than 2,700 simple and complex chemicals
• Fast - Reliable results available in 5 minutes after initial sample preparation
• Test results highly correlated with other widely accepted toxicity test methods
• Excellent correlation with HPC test methods
• Fully portable - lightweight with sturdy field carrying case
• Battery life of up to 8 - 10 hours with typical use
• Compatible with widely available ATP test kits*
• Manufactured in a certified ISO 13485 quality system with 100% lot traceability

Microtox® FX is designed for use in any sample location throughout the water distribution or industrial waste water system. It is particularly suited to remote sites such as reservoirs, storage tanks, ocean or lake going vessels or in any hard to reach place.

Chemical contamination of drinking water and wastewater

Microtox® FX is the portable version of the industry-leading Microtox® Model 500 (M500) laboratory analyser. The Microtox® FX test is fast, simple to conduct, uses small sample sizes and is very cost effective. Results correlate well with those from other toxicity bioassays such as fish, daphnia and shrimp. Microtox® FX is used extensively in the measurement of toxicity of "fit for use" water and wastewater treatment effluent. It is also used as an early screening tool for relative toxicity as part of a test battery.

Microtox® FX test systems are uniquely suited for drinking water surveillance where supplies are monitored regularly and at strategic points. It can quickly reveal any changes in the level of toxicity of drinking water making it the ideal solution for major events. Microtox® has been deployed during the Summer Olympics beginning in 1984.

In industrial and municipal wastewater, Microtox® FX helps assure compliance with NPDES toxicity limits, measures toxicity in influent streams and determines treatment efficiency.

Microbial contamination of drinking water

Microtox® FX can rapidly estimate the microbial concentration of a drinking water sample to a level of 100 cfu/mL without additional filtration or incubation steps. The data is available in minutes and is highly correlated with standard heterotrophic plate count methods.

Microtox® FX is extremely responsive and has been designed for use in a wide variety of applications where it is crucial to rapidly determine the biomass of a sample.

Applications

• Drinking water monitoring
• Emergency response: Biological contamination
• Emergency response: Chemical toxicity
• Hazardous waste
• Industrial effluent
• Industrial process water
• Municipal effluent
• Recreational water
• Soil
• Sediments
• Storm water

Process explained

The Microtox® FX system performs a dual function; toxicity testing and determination of microbial contamination. The Microtox® FX test system uses a strain of naturally occurring luminescent bacteria called Aliivibrio fischeri to provide acute toxicity detection. The bacteria emit light as a natural part of their metabolism. Exposure to a toxic substance causes disruption of the respiratory process of the bacteria resulting in reduced light output. The Microtox® FX photometer measures the light levels before and after addition of the sample, and the reduction in light output is a measure of the toxicity of the sample.

All organisms contain ATP as their main energy source and the amount of ATP in a sample is directly proportional to the biomass of the sample.

ATP reacts with luciferin/luciferase, the enzyme system present in firefly tails, to produce light. In the reaction, each molecule of ATP produces one photon of light; the light output of this reaction can be accurately measured using the very sensitive Microtox® FX instrument.

90000-27 Traceable Extreme-Accuracy Digital Thermometer with Calibration, 37.00°C; 1 Stainless Steel Probe by Digi-Sense

Four Traceable International Standards Digital thermometers provide the exact readings required for critical requirements, quality control checks, and routine measurements. Units read 0.00, 25.00, 37.00, or a combination of all three with a resolution of 0.01° and an accuracy ±0.05°C within ±2°C of standard. Units read in °C and °F.

Stainless-steel probe supplied with units shows the slightest temperature change. Probe is triple purpose for liquid, air/gas, and semisolids. Accurate readings with tip penetration of 1/3-inch. Probe has a diameter of 1/8-inch, stem length of 6-1/4 inches, overall length of 9 inches and a cable length of 5 feet. Absolute high-precision thermometer is ideal for measuring temperatures in water baths, cuvettes, gas systems, reagents, standards solutions, ovens, incubators, pharmaceuticals, petroleum products, foods, and wastewater. The display shows minimum/maximum and current temperatures. MIN/MAX monitors readings overnight, on weekends, or for any time period and displays the exact time and date when the MIN/MAX temperature occurred. Alarm provides two visual (LEDs) and two audio alerts when temperature rises above or falls below high and low set points. Unit displays the exact time and date when dual thermometer alarms are triggered. Alarms are programmable in 0.1° increments. Visual and audible alarms signal continuously (for days) even if temperature returns to non-alarm range. First thermometer ever designed to permit user one-button calibration.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
