The dye on this pH Indicator Strip is substantively bound to the cellulose fibers. 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 strips can be left in the solution until the final color change is completed.
- Indicator dyes will not contaminate samples and colors will not run into each other.
- 6mm x 5mm indicator papers are sealed on a 6 mm x 85mm plastic strip.
- Strip is sufficiently long to avoid contact between fingers and test sample.
