pH Indicator Strips (non-bleeding)

pH indicator strips allow for simple and rapid measurement of pH in a wide variety of aqueous solutions. 
Unlike our pH paper range which may bleed dyes into the sample, the dyes used for our pH indicator strips are chemically bonded to the paper. 
This means that these indicator strips will suffer from no dye loss into the testing sample, regardless of its pH. 
This feature enables these strips to be used for the pH measurement of weakly ionic solutions as they can be immersed in the sample for extended periods of time.
