Frequently asked questions
What is the measurement range of these pH indicator strips?
The Cardinal Health pH indicator strips have a measurement range of 0-14 pH.
Do the dyes in these pH strips bleed into the sample?
No, the dyes used in these strips are substantively bound to the cellulose fibers, which prevents color bleeding, ensuring accurate readings, even in strongly basic solutions.
What are the dimensions of each pH strip, and are they long enough to avoid sample contamination with fingers?
The strips are 6 x 5 mm indicator papers sealed on a 6 x 85 mm plastic strip, which is long enough to prevent contact between your fingers and the test sample.
Can these pH strips be used with unbuffered solutions?
Yes, these pH indicator strips are suitable for unbuffered and weakly buffered solutions because the strips can be left in the solution until the final color change is completed.
How do these pH strips prevent sample contamination?
These pH indicator strips are designed with an extended plastic strip (6 x 85 mm) to prevent sample contamination. This length ensures that your fingers do not come into contact with the test sample during use, maintaining the integrity of your results.
What materials are these pH strips made of?
These pH strips are made of cellulose fibers with dyes that are substantively bound to them, and are sealed on a plastic strip.
Can these pH strips be used to measure pH value in weakly buffered solutions?
Yes, 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.
Do the dyes bleed when wet?
Yes, the Cardinal Health pH Indicator Strip features dyes that are substantively bound to cellulose fibers, which prevents color bleeding. This ensures accurate and consistent readings, even in strongly basic solutions, as the colors will not run into each other.
Is the plastic strip long enough?
Each plastic strip is 6 x 85 mm, which is an extended length designed to prevent direct contact between your fingers and the test sample, minimizing contamination risks.
Can I use these for weakly buffered solutions?
These strips are designed to remain in unbuffered or very weakly buffered solutions until the final color change is complete, providing reliable measurements where traditional methods might be unreliable.
