PH test strips
Recommended for pH measurement in weakly buffered or strongly alkaline solutions
pH-Fix indicator sticks are for the rapid measurement of the pH of a water sample.
Additionally they can be used for monitoring the pH of a sample during analysis to avoid errors due to weakly buffered solutions.
For this purpose pH-Fix indicator sticks are clearly superior to other pH papers. In contrast to conventional indicator papers, the indicator dyes of pH-Fix sticks are chemically bonded to the cellulose fibres. As a result the possibility of colour bleeding, even in strongly basic solutions, is avoided.
Furthermore there are the following advantages:
- Measurement of pH values is possible even in unbuffered solutions, since the sticks can be left in the solution until the final reaction colour is obtained.
- Test samples are not contaminated by the indicator dyes. Thus solutions can be used for further investigations.
- Colours of the individual colour fields cannot run into each other. This allows a more precise comparison the colour scale.
- Specially developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison with the colour scale.
Length and stability of the plastic strips protect fingers from contact with the test solution.
