Merck pH Indicator Strips 109535 Universal – 100 strips

The MQuant pH test strips are suited for all media in environmental analysis and in industrial in-process controls. A special method of manufacturing gives the pH indicator strips decisive advantages over the 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 colour scale, perfectly matching the reaction colour. The clever Safetyedge boxes allow for safe storage and convenient withdrawal of the test strips.
