Livingstone Universal pH Indicator Strips Litmus Paper, pH 0 to 14 with Colour Chart, Non Bleeding, Biodegradable, 100 Tests/Pack

Our pH test strips are suitable for environmental analysis and industrial in-process control across all media. Produced using a specialised method, they offer clear advantages over conventional indicator papers. The non-bleeding indicator prevents dye leaching, allowing the strip to remain in the sample without contamination. pH is determined semi-quantitatively by comparing four reaction zones with the colour scale for accurate matching. Supplied in a SafetyEdge dispenser box for safe, hygienic use. Colour transfer may occur; always test before use.
