Test Kits
In this category we offer you high-quality test instruments, indicator papers and indicator strips from various manufacturers. The majority of the products are rapid tests. They offer the advantage of a quick determination of results on site without the need for any further aids. In addition to numerous pH tests, we also offer rapid tests for the determination of water hardness and oxygen in water samples, chloride, ammonium, iron, nickel, manganese, nitrite and milk.
Macherey-Nagel offers a large selection of rapid tests, among others with its QUANTOFIX and VISOCOLOR product lines for water analysis. The QUANTOFIX test sticks are ready for immediate use (on site), deliver results in seconds, require no calibration, maintenance or accessories. The VISOCOLOR products are colorimetric and titrimetric test kits, which are visually evaluated by comparison with a color chart without additional accessories. Thus, for example, the water hardness, the concentration of chlorine, iron, phosphate etc. in water samples can be quickly determined.

Test kits and indicators
So-called indicators are used to observe and monitor a chemical reaction. An indicator is a substance that makes a change of state or reaction apparent. It can be a color, for example. A process becomes obvious by a discoloration, turbidity or a change in color.
The so-called test kits are kits that contain reagents for the detection of a certain substance, a compound or an element. The methods work according to photometric, chemical or calorimetric determinations. All materials required to perform the test can be found in such a kit. No further tools are necessary for the evaluation.
In addition to kits for the determination of the pH value, we also carry test kits for determining the concentration of iron, copper, manganese, phosphate or chlorine. We offer various product lines of different manufacturers. Macherey-Nagel offers with its QUANTOFIX series test sticks for the determination of a variety of analytes. The AQUADUR test strips, on the other hand, have been specially developed for the determination of water hardness. DiaQuant rapid tests are intended for analysis in the dialysis field. Merck also offers a range of visual tests in the form of test kits and test strips from pH measurement to the analysis of turbid and slightly colored water samples. The test strips are known under the brand name "MQuant®" and provide fast and reliable results in food, water and environmental analysis.
