The MQuant pH indicator strips have a decisive advantages over the normal indicator paper: since the indicator does not bleed, the strip can be left in the measurement medium without contaminating it.

Using these test strips is fairly easy, the pH value is measured semiquantitatively by visual comparison of the four reaction zones on the test strip with the fields of the color scale, perfectly matching the reaction color. 

pH value plays a highly important role in biochemistry, chemistry and technology. It affects numerous chemical processes. The results of many analytical methods are influenced by the pH of the solvent or buffer.
