H Indicator Paper 7.9 - 9.8, Pack of 100

Details

In contrast to conventional indicator papers, the indicator dyes of pH-Fix sticks are substantially bound to the cellulose fibers. Recently developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison to the color scale. As a result, the possibility of the color 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 color change is completed. Test samples are not contaminated by the indicator dyes. ph range: 7.9 - 9.8, ph graduation: 0.2/0.4
