117925 Chlorine Test Strips, MQuant, Merck

MQuant® Chlorine test strips (117925) are designed for the easy and reliable detection of free chlorine. The test is based on a redox reaction where chlorine oxidizes an organic compound on the test zone to form a violet dye.4 The intensity of the resulting color is proportional to the chlorine concentration, which is then determined by visual comparison with a standardized color scale provided on the tube.5 These strips are an essential tool for rapid screening on-site, ensuring that chlorinated disinfectants are used at effective yet safe concentrations.6 As part of a sustainability initiative, the product now features a recycled aluminum tube and a reduced strip width to minimize environmental impact.
