MANTECH’s revolutionary peCOD Analyzer technology measures the chemical reactivity and associated oxidative changes in Natural Organic Matter (NOM). As a result it is more sensitive than Total Organic Carbon (TOC) and UV254 to changing NOM concentrations in source and treated drinking waters.

Two innovative instruments for TOC analysis, uniTOC online and uniTOC lab, combine high-end analytical components certified to DIN EN 1484. The graphical control with the 10” touchscreen display and the data management of the control and analysis software meet all international standards for the determination of TOC.

The instruments are designed for monitoring process water in areas such as pharmaceutical, microelectronics or chemical applications, as well as the production of potable water or ultrapure water. With the uniTOC analysers, membraPure provides the perfect instruments to meet the demands of the existing regulations.

Astacus² models are designed for a daily consumption of less than 100 l and are equipped with a MemPak purification cartridge. The Astacus² water purification system is available in different versions (Reagent, Analytical & LifeScience) to meet the specific requirements of ultra pure water for different applications. The systems also have the new fixed and flexible dispenser and a big touchscreen with easy to use menus and wizards.

MC-Media Pad® tests are designed for convenient and reliable testing of E.coli, Yeast and Mold, Coliform, Staphylococcus Aureus, or aerobic microbial contamination in food and beverage products. MC-Media Pad® for testing of coliform, aerobic microbial contamination and yeast & mold is now available in the US and Canada.

The pads have a multilayer structure, which allows the sample to diffuse into the pad evenly without intervention. The use of specific indicators and chromogenic media means that the read-out is clear and rapid.

The Spectroquant® Move 100 is all you need for rapid, reliable water analysis when working on site. That’s because this small, portable colorimeter covers every important parameter of drinking and waste water analysis in one instrument. With a choice of over 100 pre-programmed and 35 user-defined methods, you will always have the most suitable test for accurate results – on the spot. This means no delays, no risk of sample deterioration, and no need for additional instruments.

The Spectroquant Prove family is our series of cutting-edge spectrophotometers for easy analysis of water, food and beverage, and environmental samples.

Merck’s Membrane filtration technique complies with international standard such as standard methods for Examination of Water and Waste water, US EPA, and EU testing procedures for drinking water or other filtration testing it’s simple: the test sample is filtered through a microporous membrane, allowing the retention of microbial contamination on top of the membrane. Rinsing removes residues that might inhibit the growth of microorganisms. Once the sample is filtered, nutrient medium is added to promote growth of microorganisms for recovery. For testing non-filterable samples, Merck offers a large selection of culture media of the high quality.
