Colorimetric Test Kits by Merck KGaA, Darmstadt, Germany

Each pack contains all the reagents necessary to carry out a test and everyone can use them even without special chemical training. The high-quality color cards decisively simplify the allocation of the samples to the stated values. This gives you more precise results in no time at all. Another unique feature is that test kits and comparison colors are adjusted with the aid of certified standard solutions. These can be traced back directly to primary reference materials originating from NIST und PTB. This provides a consistently high quality standard for all our visual test kits. When stored at temperatures between 15 and 25 °C, the test kits remain stable for up to three years from the date of production. Also, there are practical refill packs. These allow the use of color comparators over and over again – which reduces costs and is environmentally friendly.
