Product Details


In contrast to conventional indicator papers, the indicator dyes of pH-Fix sticks are substantially bound to the cellulose fibers. As a result, the possibility of the color bleeding, even in strongly basic solutions, is avoided. Furthermore, there are the following advantages: 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. Colors of the individual color fields cannot run into each other, thereby allowing for a more precise comparison with the color scale. Recently developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison to the color scale. Sample application - four different indicator papers 6x5 mm are sealed on to a plastic strip 6x85 mm. The strips are sufficiently long to avoid contact between the fingers and the test sample. pH-Fix™ Indicator Sticks are packed in a box of 100 sticks 6x85 mm.
