In contrast to conventional indicator papers, the indicator dyes of pH-Fix sticks are substantively bound to the cellulose fibres (DE-PS 24 36 257). As a result of the possibility of the colour bleeding, even in strongly basic solutions, is avoided.
Measurement of pH value is possible even in unbuffered or very weakly buffered solutions since the sticks can be left in the solution until the final colour change is completed. CE marked versions available.
